They damaged my vehicle, and not finding a solution to fix it. HORRIBLE SERVICE

My vehicle was towed to Renew-it Sandton in March this year after a small bumper bash. I immediately requested for my vehicle to be moved to Centurion as I stay in Centurion. After quite a struggle to have my vehicle collected from Renew-it, we noticed that my vehicle was damaged on the front right fender which was not there at the time my vehicle was towed. After quite a few emails between my insurer and Renew-it Sandton, guilt was admitted by Renew-it. They have agreed to fix my vehicle at their own cost. However, they wanted to leave me without my vehicle for 5 working days which is just not possible. After another few emails I was promised that a courtesy vehicle will be bought to me and they will collect my vehicle in Centurion. Weeks have passed where I need to keep following up with them, just to get the same feedback that they will have a courtesy vehicle for me by the next week. It has now been months, and still nothing has happened. I have gotten through to the Operations Manager (Lyle) who also promised to have a courtesy vehicle ready for me within a week., again empty promises. I am now at wits-end. I am not receiving any feedback from them. How can they possibly try to leave me without a vehicle for 5 days, so that they can fix the damage that THEY did to my vehicle? How am I supposed to get to work and back? This is the most horrible service that I have ever received from all of the companies that I have worked with. Shame on you Renew-it Sandton!
