Horrible Service

I received confirmation that my claim with PMD was approved on the 09/03/2023 and NU Wagon Autobody was the authorised Autobody to fix the car and I have never received any communication from them. I was the one who would call them and they would send me from pillar to post. Until I decided to visit the Autobody myself on the 06/04/2023 and the state that I found my car in was horrible, my car has been completely been stripped and they can not even tell me why?. I found multiple oily parts in the back seat of my car with the seats uncovered and it seems it is now being used as a storeroom for parts, It has multiple scratches which were not there in the first place when my car was collected from my residence. The service I have received has been the worst, to this day I still do not know what is going on with my car.
