POOR SERVICE!!!!!!!!!!!!!!

Took vehicle to Renew it Edenvale for repairs after an accident in Sept 2018. Ever since than my vehicle has never been the same!!! My car makes a rattling sound that seems to come from my front right hand side starting from 80km/ph while driving on the highway – I replaced the tyre and it was confirmed that the suspension is bent. Interior components are rattling. Each time I hear a grinding noise during a tight turn in the parking lot, my right door is retaining water after I had drove through high water. Interior components are rattling. I visited Renew it on 3 different occasions, each time they say they would get back to me but I have received no response. I initially reported in Feb and to date no progress.
