Rolls door were great door worked well for 6 months then it went wrong. Company accused me that it was my fault and basically called me a lairer when i offered my explanation of why it went wrong .they sent a team out to fix it which they did well.they then tried to charge me £81 for this even though the door was only 6 month old. I said I was not going to pay as it should be covered by the guarantee.they they replied that they were not going to honour the guarantee. If it goes wrong again I will take them to trading standards as they clearly supplied goods not fit for purpose.my advice spend a bit more with another company and get better service
