Treated like trash

4 months ago I paid R2500 for repair of my USB port, and just a month after that it's was broken again, and thought to bring it to their attention when servicing the vehicle, and I did. Was told that it's my fault, hence they will not fix this, and the service assistant said will call Mercedes Benz and return to me next day, and it's now 4 days I have not heard nothing.

Plus the way I get treated there is like am some sort of a third class citizen, and I did give them this feedback when I was called for review.

I love my car, but the experience sucks, to buy an expensive vehicle and be treated like trash.
