Hi, got new roller blinds fitted this morning, including one on the front door which is half glass. When the guy left I opened the front door and it would only open halfway!! The blind and bracket are hitting off the wall behind the door. Im really peed off! Should the Blinds people have told me this would be a problem or is it my fault?! I cant understand this as most of the estate have a roller blind on the door.......can anyone advise me what I can do?? Not having a blind is not an option as the glass is clear........Thanks in advance!
