No due diligence regarding their service providers

Discovery booked ( they do not do Due diligence regarding service providers, there are plenty complaints on internet regarding these service providers) my car in at Brooklyn motors after the assesor ( net assets) that's right next door to them recommended it. Steer clear of this assessor and panelbeater as they work together and damage your car more than the Initial damages. Discovery and the assesor said it will take 5 day, Brooklyn motor lab said 10days and my car is still there after a month 30 days with more damages which they claim was there when I took it in. I requested the assesor s check sheet where I signed indicating chips ect but this sheet is no where to be found and I'm charged for all additional damages that they caused due to poor blending and over spray. They messed paint inside my car on the seats and dash and the work they claim is done is done with no pride the one front panel was painted with a paint brush and you could see the lines of the brush. They messed up my side skirts and said it was like that. The sapose to be new bumpers has chip marks and plastic welding cracks which I must pay additional payment to fix Please stay clear of this place and the assesor next door. I asked for the initial assesor qoat indicating faults before panelbeaters but surprisingly it's not found via any of the parties involved. The complaint department of discovery is non existing, they did not intervene once during all these complaints only now after 30 days someone contacted me from discovery
