Damage to vehicle - Renault Stikland

I had my vehicle serviced at Renault Stikland on 16 April 2018. My vehicle was returned with damage ro my lefr front fender. I reported it the same day and emailed pictures to Theresa. This escalated to management and they admitted it was thwir mistake. Since then I have phoned, emailed and deove their regularly to get it fixed. I have on numerous occasions communicated with Theresa who kept on saying that Eugene the manager will contact me and I will be included in on the email informing him. Now my emails and calls are ignored. No email received and to this day not heard from Eugene. After driving there numerous times I spoke ro another manager from Jhb, John Rogers and he said he will address this with Eugene and get him to contact me. He will address this matter and get Eugene to sort it out. No response from Eugene to date. I went again to their office and spoke to the acting manager Robin. He gave me his email address and contact number apologising for poor service rendered. He promised he would send Eugene an email and CC me as well. Not surprisingly, no email received and no communication from Robin or Eugene. This is on going for more than a month and my vehicle is not fixed. Left hanging with empty promises, lies and deceit. Do you have any idea who I could contact other than these people. Clearly Renault does not take pride in their name and service they render to their clients. Let alone no so they show any respect toward the client by they lies and misleading principles. Very very unhappy client. Poor poor service, putting it mildly.
