We have had numerous problems with our supplier.The latest after 2 years they have agreed 2 or 3 panels where cut too short and have replaced same with a new company to an apparent exact match.The panels look different in colourbut we are assured they will wear in very quickly.I have my doubts and our guarantee runs out in 2 years time.What do you think Help PLEASE.The roof is an ultraframe roof.Sofar the supplier hasnt put this in writing as requested shall i confirm his comments to me?
