7 Months without a vehicle and still not fixed

So after paying over 50K, 7 months waiting and a 1000km's put on my vehicle with boot damage dents and the incorrect battery put into my car by MegatronicsSA in Wynburg, my car was taken to a Audi approved dealer this Tuesday for an accesment and the outcome is that we are still sitting with 55K's damage on the gearbox so my honest opinion the original gearbox was put back and we where told by Megatronics SA Wynburg that the gearbox is as new we paid for a complete overall on the gearbox and the gearbox is still not fixed and then the car gets given back to us telling us that it will still give problems as it's in adaptive driving so for 7 months they have been bull****ting us and *****ing our money they are the biggest ****** I have trusted with my car they are just a bunch of ****s *****ing people's money
