Ordered bifold doors worth £4k. Delivery was a bit late but got installed in the end. Then after 6/7 months there were paint issues. Paint flaking off and a bubble was formed in paint in one of the panels. Reported to Alpine and they sent an engineer to come and have a look and agreed to replace the panels. Then when no one turned up, I contacted customer support and to my surprise they said they need to send someone again for investigation as the manager is replaced and new person has joined. The other engineer investigated and said its our fault which isn't true due to the way paint is flaked and bubble is formed in paint. Since then I am back and fourth with them. Last time told a new person is joined who will contact me who takes care of all warranty issues but no one is contacted even after weeks. Very poor after sale service so I would say avoid this company.
