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..,

Hello Madam, Thank you for your message. We fully understand your disappointment regarding this situation, and we kindly ask you to accept our apologies for this inconvenience that is beyond your control, as well as ours. Indeed, the carrier has confirmed to us that the package was damaged during transport and deemed undeliverable, which resulted in its return without prior notification – neither to you nor to our service. We regret this lack of information and will take the necessary steps to prevent this from happening again. Best regards, Dominique / SLID'UP Customer Service

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.

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.

Therefore, we have internally reviewed your feedback to improve our service - but in fact, we found no message from you, and no call took place either.

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.

Please excuse the problems with the shipping: Unfortunately, your announced shipment could not be delivered, the deliverer did not find you. The shipment then waited in the parcel shop in vain for pickup and was subsequently returned to us. That the customer then at least pays the shipping costs is not unusual, although the return even incurred further costs. Unfortunately, our inquiry for another delivery went unanswered - we have now also refunded you the 4.95€ as a goodwill gesture. Best regards from your team at slidup.de

Hello, We sent you the instructions for returning your order on January 16. The package has not yet reached us. Regarding the next order, unless we are mistaken, it was placed on our site on January 13, it was handed over to the carrier on January 14 and it is noted delivered on January 16. These delays correspond well to the delays announced on our site. We hope that despite your dissatisfaction regarding the delivery, the item suits your project.

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.

Thank you very much for the feedback! In fact, the shipment was delivered two days later - but that was of course much too late. Unfortunately, not only the Christmas holidays caused delays for us and the shipping service provider. Meanwhile, shipping is working quickly again as usual. Feel free to try it out!

Hello, We are sorry that we could not respond favorably to your request. We confirmed in our email of June 20 that the 3m rail alone in the Slid'Up 160 range is not available for sale. We only offer a 1m94 rail. We offer a complete kit including a 3m rail. However, being a distribution center, the items we sell are pre-packaged and we do not do unpacking or custom work.

Attention, it is not mentioned, but exchanges are simply not accepted, you will have to return at your own expense. Given the size and weight of the items, let me tell you that you do not have the right to make a mistake! Fortunately, in my misfortune, I found much cheaper at Avosdim, so I was able to offset the return costs, with a responsive customer service!
