Stay away from Mr Gutter

Appalling service. Mr gutter installed new gutters for me at the end of 2018 and they leak back into the house. (The gutters they removed did not leak). They've been back 3 times and haven't fixed it. Now they tell me it's my roof that's the problem and are only prepared to come 2 days before xmas to try to fix it again. They also tell me the problem is my roof not their gutters. Appalling workmanship and just a mess around service
