Roof repair *******

I have had this company try and repair my roof on 3 different occasions. The first time they fixed the roof over the lounge and bathroom areas. Unfortunately the roof continued leaking over the bathroom area and after numerous attempts, they finally managed to fix the leaks. Then they came and attempted to fix a leak in the passage area, which to this day has not been completely leak proof. I kept faith with them. hoping by doing so they would fix the problems in the passage and asked them to fix another leak that had occurred in the bedroom area. This is the one area they could never get right and I had to call them on numerous occasions to sort out this problem. Despite being given a 3 year warranty which still has about 8 months left before expiry, they point blank refuse to honour the warranty and are now laying the blame on me for not properly maintaining the roof. I am not sure what maintenance I could possibly do that would make the leaks go away. They charged me R9,500 for something they did not fix properly and refuse to honour a written 3 year warranty. DO NOT EVER USE THIS COMPANY FOR YOUR ROOF REPAIRS. THEY WILL RIP YOU OFF.
