Disappointed with Miway and Bradbury auto.

Miway took my car to their approved panel beater, Brad bury auto. Those people messed up my car and when I call Miway to complain they say I should talk to the panelbeaters. I have had a problem with Bradbury from the first day they had my car and Miway now wants me to deal with the panelbeaters all by myself. My wipers are not working, push to start is not working, I have to insert key to start the car, can’t lock the car because the car can’t detect the key, the lights fill up with water when raining and the under cover was fastened with permanent *****s which will make it impossible for future maintenance. Miway has really failed me as a client and I am very frustrated and disappointed to a point where I will be cancelling my cover with them.
