Original parts removed

I took my car for auto-body repairs. When it came back the power stearing Was dead it was so hard. I took it to a qualified and registered mechanic they noticed that the power Stearing pump was changed. There was even one bolt missing. The airbag system was no longer functioning only god knows what happened. The fire resistance cover for the front bonnet was missing. I have never sern anything like that. I had the baddest experience and I wouldn’t recommend them to anyone.
