Glasfit damaged my car.

thank you very much for damaging the centre mirror coves and the cover at the bottom of the windscreen on the outside. i have instructed my insurer to never use glassfit again. bit of a backstory. the last windscreen replacement that you guys did, the guy told me he cant put the covers back because the clips are broken. so i said to him glassfit did the last one, then he responded by saying cant help with that, speak to VW. So now its time for another replacement and the new guys show me the broken cover on the outside as well. so Whoopi doo, another part i have to buy from VW because of your incompetence.
