Shocking service by Brooklyn Motorlab

I was referred to Brooklyn Motorlab, Koedoe****rt, Pretoria by Discovery at the beginning of August 2020 after having an accident with my Peugeot 208. I also asked them to do additional work to the car for my own account (replacing the mirrors, taking out dents and scratches, etc). They did not receive the right mirror on time so I had to take the vehicle back on 24 September 2020. The lining of my front bumper was shoddily put in place. It came loose on the highway on my way to have a final mirror fitting on the car as Brooklyn ML. David Twala admitted that it was due to bad workmanship from Brooklyn ML that the lining came loose and that this part would be replaced free-of-charge by Brooklyn ML. After threatening that I will publish a complaint on hellopeter.com and other public consumer sites, write a letter to all the major insurance companies complaining about the non-service from Brooklyn Motor Lab, write a letter of complaint to Peugeot SA (for whom they are an Approved Supplier) and initiate legal action including lodging a complaint with the CGSO - Consumer Goods And Services Ombud. I got a call from David saying that they have the parts and the job will be done the following week. The same afternoon I got a call from Nelia Hunter asking me to send them photographs of the damaged parts so that they are sure they have the right parts. It has now been nearly 4 months since they promised to replace the parts and I have phoned 22 times sent 4 emails, and each time I am told that they will check the storeroom and get back to me. This morning I called them in a last attempt to sort this out before I take the steps listed above… and I was once again told by David that he would check the store room and call me back by 10:00. I am still waiting.
