Unfunctional part used to repair a vehicle

I had a claim, the vehicle was repaired, but the mirror is not working. I was advised that the brushes of the mirror are finished. The technician came to my house and the mirrors were adjusted manually. I still cannot adjust it on my side. To date I haven’t heard anything from the panel beaters, when I call, am given a number of a manager. Am just being send pillar to post. I have contacted your claims department, am getting the same response that are following up.

A non-functional part was used on the car. I need to know why a non-functional part was used, as I pay my premiums every month and the car was supposed to have been restored to it’s original state.

I’ll be taking the matter to the Ombudsman if I don’t get a resolution as soon as possible.
