Customer reviews of SLID’UP by Mantion

Package 00K6NGGH announced delivered but not received from GLS

I had an awful experience. The customer service manager should be replaced. He is rude and mean. This is no behavior to have in any position. A piece broke up assembly and he denied replacing it and I had to fight with him to have it done. This is ridiculous behavior. His attitude towards others is really bad and your company should really really ashamed of his interactions with costumers. He made me hate ever giving your company my business. At one point I wished I had never bought the sliding door hardware at all. That’s not what customer service managers are for usually. Usually they are able to keep the situation calm instead of saying ignorant things to upset the customer. He really needs to grow up and not act like a child when responding to customer emails. My first email response to him told Him he should have had a coffee before he responded to emails in the morning because it was so poorly done. It attacked me for a late purgatory delivery. This whole experience has lost any future business I may have ever given you. Not that the piece is replaced my dole works amazingly and I love the hardware. To bad I have nothing but negativity left for your company. Good product. Really shitty staff that needs to obviously be retrained and taught how to appropriately handle their workload. You would think at such a high price point your employees would have to knowledge on have to deal with defects appropriately. You guys are by far the cheapest out there. I really did honestly expect more from your company.

Tried to engage customer support with help on a faulty product. Was not seeking any monetary compensation or replacement. Was told that they could not address my issue or provide any support because their failed roller on my sliding door was purchased thru a third party. Doesn’t surprise me that a company with poorly designed / faulty products also has very poor customer service. Would most definitely seek other options for your accessory needs. Be wary of the weight ratings and plastic components used in their products. We had to failures on two different doors (all within their specs) in less than a year. A significant pain and expense. We replaced with another manufacturer’s product and have been very satisfied with the design and use. No plastic parts to fail..,

Defective item.

package not received, returned to sender without reasons. the delivery was rescheduled, then absence of delivery and return to sender, without the carrier contacting me. no feedback from slid up for now, to return the ordered product or refund me.

a delivery error because I received 6 rail supports out of the 7 normally present... I hope this will be enough to hold my door ...

I'm not very happy with the delivery, too much delay, I trusted this service a lot but in the end they upset me, they made me lose the day for placing the part I bought from you. In the end, I didn't do it, I set it aside, I lost my workday and I wasn't paid.

Still nothing received. The GLS delivery person says they put my package in Looker since 08/07, but I never received an email or SMS with an identifier and password… so impossible to retrieve it. Impossible to reach GLS on the weekend and tomorrow is a holiday on 14/07. So I'm lost and I've been living in darkness for over 12 days because my roller shutter is broken in the closed position.

I have shopped several times, the company reacts very quickly when I leave money, but when I wrote about the desire to return one profile, it was silent as if sowing poppy seeds. Well, it is evident that customer satisfaction is not a priority.

Order placed on 20/06, delivery 2 to 3 days but still nothing received after 8 days.

disgraceful delivery service.

Still haven't received my order from June 30, 2025. GLS notified me of delays twice with rescheduled delivery dates...

Package received empty at a pickup point... I therefore refused the package... I am waiting for a refund from you.

Too difficult to give a score. The merchandise seems fine but the system of references to order is very confusing. Do confusing that I apparently ordered the wrong rail. Though it seemed obvious to me that if you order 3 rails they would all be the same size. . I was told it was my fault and returns were not accepted. This treatment, in the modern world of internet ordering is not only unacceptable but also probably illegal in the consumer code.
So, shape up, Slid'up, be amenable, be nice.

Very disappointed I buy directly from the manufacturer, to avoid enriching Leroy Merlin. But unfortunately, I encountered a problem between the size of my carts and the rail, I bought these elements separately in a kit.
I made a mistake in my order, of course, but I left a comment for your staff at the time of the order asking if, following my choice of different products, I would not encounter any issues, but I don't feel like anyone from your side read it, as a result, I managed, spent more time, but thanks to ingenuity I found the solution but not thanks to you.
So really not great your customer service, which does not read comments during orders, I wonder what the point is of writing comments.

I’ve tried calling the number that’s posted left messages nothing. I would like to start a return, but there is no way to return it that I can see or on their website. I was looking for a little bit of technical support. That’s all but at this point, I’d like to return it.

I haven't received it yet

Poorly cared packaging, consequently, the upper rail was bent on the front part.

Unfortunately does not respond to emails regarding a warranty case, therefore unfortunately paid the full purchase price twice.

mantion is negatively remembered by me

Mistaken in the order, difficulty in returning and getting something else

Did not respond to my request for additional product support.

I had an issue with my order. I was overcharged for shipping. I emailed customer service. No reply. I called, no answer. Weeks go by. I emailed again. No reply. I call again. No answer. Terrible, non existent customer service. Absolutely no response. I would not buy from them again. Overcharged and then ghosted me.

Poor quality

Delivery has not yet arrived.

Shipment was calculated and announced. However, I never received a shipment. For that, the refund of the purchase price - however with a deduction of 5€ for the shipment. For me, not a good style......

Unfortunately, I did not receive the order
I also did not receive a notification card

Order that does not match what I wanted to order I contacted for a return but no news I then have another order that is supposed to arrive but no news so I think it will be the last orders I place.....

I cannot recommend this company.
The order never arrived.
Not even an email was received with the tracking number. Allegedly, we never picked up the package at the package shop. How are we supposed to know that it is in the package shop when we did not receive any email or note in the mailbox? We find that strange.

Delivery time

Where is my order

I waited over 2 weeks for my original trak. My first order of six sets of track. When it finally did arrive, only half of it made it.
It took almost 10 days for the replacement to arrive. Very frustrating how long it took for me to receive my order.

Starting up and programming with the manual is very complicated to understand, I haven't managed to do my programming yet.

I still have not received my package, it has been 15 days that I am waiting for it

The quality of a supplier also depends on the carrier chosen for deliveries. In my case via DPD after a week and three exhausting calls (correct address) waiting for my package, on the third visit, the delivery person simply told me that he did not have it!!!

8 days after the order still not received

Review the plan, too many problems
Material needs to be reviewed, the locking screw is too long and does not allow for precise adjustment, the guide with the rollers is too long which results in a bent door that is not even parallel

Did not work on my sliding track

Cannot return product as it costs too much. Company won’t pay to return product.

My rail came in BENT from USPS in the cardboard tube and want a refund!!! How can I get my refund???
