Disgusting horrible customer service!!!

We bought an AUDI A4 in March/April 2018 from We buy cars in Montague Gardens. The sales person we bought this vehicle from is Rory Brown. When we viewed the vehicle it had 2 car keys and there was a R4000 off easter special. When we took delivery of the car they could not find the spare car key and the vehicle was dirty and filthy (i still have those pictures and Rory also took pictures which he said he will show to his manager as that was "unacceptable"). He promised and assured us that they will arrange another spare key for us (its almost 4 months now and still no spare key) . Rory also said that the R4000 would be paid directly into our finance account MFC (which we were tracking all the time and updating him every week that it still has not reflected and he kept on saying he will follow up and he never got back to us). We took the matter up with the manager Chris and he assured me that he will get the matter resolved ASAP. So now almost 4 months later and still no spare key and no R4000 (false advertising). So dissapointed in this company. is this how you treat your customers?? Now we are left with no other option but to take this matter up with the ombudsman. We will be sharing this on all social media platforms including all the pictures taken.
