BMW Fountain BAD Service

I took my car for assessment on the 31 July 2018 because it had water leakage overnight. the first day past without any feedback from the service department "1st August 2018", on the 1st i called them and was told that the person who is working on it is not available, he will call me back when he is back, but the past again. On the 2nd August 2018 the gentlemen call and mentioned the full quotation including service and tyres, and i told him that my car is not yet due to service i was just worried about the leakage., we then agreed.... on the 3rd i was told that my car is fixed but it was involved in an accident, i told them I dont want my car with scratches, and i need a car to attend a family event, the service manager told me ACCIDENT is an ACCIDENT, and they dont have any car to loan me. I ended up not attending event. I begged for loan car because i deal with clients and meetings at work but yeap they thought i was crazy woman because they would promised to call me with the feedback if they will get a car or not ,,, i didnt have a car from the 1st until the 7th after fighting with them.. Iam very traumatisted with BMW Fountains , their services id BAD and they dont take their customers/clients serious. i only a car on the 7th without a petrol. Someone from called me last week Wednesday 8th and wrote my complaint but till today i never had from him. OOOOOOHHHH BMW dont take people serious.
