Having spent over ten thousand pounds with this company, I expected a little more consideration. Turns out they only look after their own staff when it comes to emergencies. Whilst on the phone I was abruptly put on hold and without knowing somebody else eventually came back to tell me her colleague had an emergency to deal with.
THEY ARE NOT AN EMERGENCY SERVICE, this is in the small print. So, when I called them last Tuesday to tell them that I couldn't open my front door, the earliest day they could attend was on the Friday (this despite the 10 year guarantee). So, if you want a company that is likely to attend an emergency sooner, use another company. Like I said, small print.
I have also had cause to complain in the past. They replaced a window, again under the 10 year guarantee, but the new window was only covered for the remainder of the original guarantee. They can get away with fitting lesser quality windows for replacement purposes this way and that they did, as the replacement window was the only one to develop issues within a relatively short period. Again, the small print. I supplied the requested details, so that they can supposedly investigate. I don't know what there is to investigate, as the issues mainly lie with their policy.
