aaagggghhhhhh! We got double glazing installed almost 2 years ago by weatherseal but had nothing but trouble. The engineers have been out 6 times - back door jammed shut twice locks and hinges have been replaced, front door jammed lock replaced, our bedroom window slipped and we couldn't open it, daughters window slipped and draughty other windows silicon sealant rubbed away. They were not the cheapest quote we had but we thought reputation etc but when we have had to call to get engineer out timescales range from 3-6weeks which is not acceptable when we have two small kids. Luckily engineer lives locally and due to number of times he has been out we are on first name terms so when we have a problem he usually fits us in so it does get fixed quickly but surely this should not be the case or am i being unreasonable? What makes it worse is the number of sales/marketing calls we get from them i.e. do we want to recommend a friend ( i dont think so)they drive me mad -I have written to their head office to complain but not heard anything back ... any suggestions MN's
