Budget refuses to fix an issue they caused during their repair process

Budget has been fixing my car since April and to this day it’s still not fixed, during this process, my car went to about 4 dealerships , an energy draining almost a year long process where their dealerships kept on fixing and damaging at the same time.

One of their dealership partner broke my windscreen, they had it replaced , then after about a month replaced it again, claiming that it was not up to standard, now my windscreen has cameras and technology chips on it, they’re now claiming one is broken, and they will never fix it because they never worked on the front of the car, while they replaced my windscreen two times.

I really feel abused because all the technology on the windscreen has always been working, one works with start stop feature, and it’s not working now of recent, and they say they won’t fix because they never worked in the front of the car, but that’s where the windscreen is.

This is not the only damage, one time the engine couldn’t start, they they said they reconnected it, then the aircon, then they said they reconnected it, now this start stop feature they say they won’t fix but they worked directly on it.
