Krish from smg parts department

I called this branch as I bought a car from them , the car had a problem with the gear box and then called them, the receptionist put me through a guys called Chrish in the parts side, I relayed the story and immediately sprigs said he knows of someone with a gear box, gave me numbers and he said they work with them, because this was coming from him and the call I made was to the dealership I then called this number , I got the gear box and my mechanic installed it, then the engin gave in, I called Krishna again and said I wanted to bring my car there, he said because my mini is a bit old he would suggest I take it there Theo and Eugene as they deal mainly with minis and they are a part of them! I then listened to that! After paying all amounts and being told the car is ready, after a year of calling and being taken pillar to post, finally it was ready, when the gentlemen I had sent to collect the car got there , he wanted to test drive the car, the windows were not opening and closing, the gear box leaked and the car was in smoke ! I called Irish and Irish finally said he has nothing to do with them and they are on their own . I want to lay a complaint against this company for failed refferals as o called the landline and that’s where I landed at .
