Poor repairs after just 3 weeks and blocked me from contacting them

I accepted Mike's quote which to me was rather steep but I opted to use him as he would repair on the spot.. Once they started they had no idea what they were doing and said they will take it to their workshop. The disembled my dishwasher to fit it in their small red car, pls note, there guys were supposed to be professional.. After a week of no contact my husband called him and said he wants the machine back now.. The machine worked 4 times and bombed out again.. When I called them they promised to come sort but since then I've been blocked and they don't take any calls. This was literally 1650 down the drain and I'd warn anyone else before they get bitten by the same guys.
