Booked in Cumbria Superglaze to fit a new front door, kitchen window and back door. Paid a deposit of £450 on the day I accepted the quote, leaving a balance of £1450. That was the 31 October 2019. Someone came and measured up in mid-December after telling me that somehow 'they lost my paperwork' and promised it would be fitted before Christmas. Christmas came and went; no doors or window. They were finally fitted on 9 January. Almost straight away, we were called and asked for payment of the balance. My husband had the credit card, so I told them he would contact them. After another phone call from them a couple of days later, today I called to pay. I spoke to an incredibly rude and aggressive "gentleman" who I believe to be the company owner. I said I'd phoned to pay the balance on the account. "Oh, is that one of the late ones we've been chasing?" It has been 11 business days since it was fitted and they had my deposit for 9-10 weeks. Instead of just saying, 'great, thanks for phoning', he said that they can't honour the guarantee if the balance is paid more than two weeks after fitting. He super generously said they would honour the guarantee "this time". First card was declined so I said I'd call him back in a minute with another one. His response was, "You'd better be quick". When I phoned back 10 minutes later, upset and angry at the first interaction we'd had, I asked him if it was company policy to be so rude and that the repeated phone calls for payment the company engages in feels like harassment. He got very angry and said that instead of paying he could just send the bill to his solicitor. Weird, given he was so hot on getting paid quickly. I paid the bill but will never, ever use Cumbria Superglaze again and wouldn't recommend them to anyone.
