Renault brits overspray on new car

Got a brand new renault triber from the dealership .. noticed a few faults and phoned renault brits to fix as i bought a new car from them . Took 3 months to get a date to take my car in.

After bodywork was done by panelbeater i was given back a car full overspray and dirty marks where the worked on .

I took back the car to rectify..

After a week i was phoned by renault to collect my car .. It was full of dust and i told them i will inspect after cleaning the car .

Got home . Washed the car and to my horror there was still overspray on the vehicle and to add to my car problems the boot doesnt close now aswell.

They scratched my vehicle trying to remove the overspray .

The car has paint comletely removed from polishing of the overspray ..

I phoned them again . So maybe 3rd time is a charm . Thinking of cancelling my buy!!!
