Poor service from Halfway Toyota Scotburgh

Me and my brother bought a Chrysler voyager 2.8D in October 2018. We did not receive the spare key, service book and the vehicle had a few defects that needed to be attended to. The salesman promised us that the spare keys and service book were going to be couriered to us, the defects were going to be attended to at their workshop. We waited until I decided to contact them. A person called Denzel **** to me saying he was going to send me proof of service for the vehicle because I was saying to him that I've come to a stage where I don't believe anymore that the vehicle was being serviced prior to being to owned by me. He also promised that he will book that vehicle to checked and get the keys recopied because it eventually transpired that the keys were no longer available. He never did that. I tried to contact Toyota Head office using their "contact us" button on their website regarding the matter, but there was no response from Toyota. I have been waiting in vain since then. I am so disappointed with Toyota, and I would like to warn other potential customers to be vigilant when dealing with Toyota.
