Appalling service received.

My car was taken to Faber Montague Gardens after a fender bender, it was Discovery Insures preferred supplier that they allocated to do the work. I received the most appalling service. I never received feedback, I continually had to check in with the progress, I had to phone the parts consultant at Mahindra myself to get feedback on where my parts were, the incorrect parts were ordered for my car which I was informed about on the day I was meant to collect the car (Only because I followed up about what time i could collect) and lastly when I fetched the car the open door sensor was damaged and wont turn off. All delays were blamed on loadshedding. I have no trust in this company.
