Disappointing and time wasting

After taking my money, blocked my car in my garage for 3 weeks with scaffold (was only supposed to be a couple of days) , come back over a few weeks to rectify problems, stupidity on my part over the last few weeks been emailing them (had one response to say someone will be in touch) I’ve called many times and since but nothing, I was only using them as needed a couple of extra windows for a extension and wanted to make sure they match the existing, we built the extension quicker than any response from them, they are expensive but sure you could get same quality elsewhere cheaper, AVOID
