Bad service

I am severely disappointed by the service I received from this company. My insurance took my car for repairs to this company. Vanos Tech called informed that the car was fixed thus I can come collect it which I did. On my way back home, the car started showing a light which was an indication that it was not properly fixed. I reported this and they advised that they will be collecting the car which they did. I was advised by the receptionist that they fitted an incompatible part to my car but they are ordering a new part. I spoke to my insurance regarding the courtesy car and my insurance informed that the repairer should organize me a car since they did not do a proper job. I am now without a car for 8 days, I have to use Ubers to work and with my 2 kids going to 2 different schools. The only person who is calling me is the receptionist and she advised that she is conveying my frustrations/complaints to the management but no one has bothered to contact me. I paid but now I must spend so much money to move around, this is not fair. Where must I get all this money to move around?? Worse of all, no one is bothering to give me a call except for the receptionist who is trying the best she can buy she also cannot answer my questions which is understandable. Is there no management in this company??? No courtesy, using this receptionist to call me is not addressing my frustration!
