It started in the shop. Once you've paid, they make it clear to you that you will do as you are told. They give a very rough idea of delivery date, and it's clear that it will happen when it happens, and if you don't like it, that's just too bad. They have a weird arrangement with the fitters. You have to pay them in cash on the day. The actual fitting job was fine, except for the twin heaps of carpet fragments of snipped metal they left behind.
Problem was... three of the doors now refused to close. Hence the quick disappearing act. We contacted SCS who suggested we pay for a joiner to adjust the doors. Not their problem - modern carpets have deep piles. I asked why nobody had brought up this possibility, even when they made a personal visit to measure up. Anyway, they said they'd send someone round.
That was all three months ago. Not a word from them since. I suppose they reckon that if they just ignore you for long enough, you'll end up trimming the doors yourself, which is what happened.
Conclusion? Just don't. They don't care about their customers. From the second you sign on the dotted line, they couldn't give a toss.
Go somewhere else. Please.
