Unacceptable service

I bought a car at their Zambezi branch on 12/12/17, I was assisted by Mr Matsimela Kekana. The problem I am having is that I always have to run after them, I have not received the spare key for the car while I was promised to have received it when the number plates were installed. Secondly, the number plates were installed on Saturday but I still do not have the disc and that’s because I went to the post office yesterday around 13h00 and when I got there they requested for a road worthy certificate, I called Mr Kekana and he said he will send it. He only sent it at 16h32 and the post office was already closed. The email he sent me, he attached the original email and not the document so I still cannot download the certificate, I made him aware this morning and he resent the email but still I cannot download it because he attached the email and not the document itself. I told him that I still cannot download it and he said I must use the picture he sent me via WhatsApp.

They are taking advantage of me as I am a young ladyand their service is very poor. I need to fetch the disc today and I need a professional email with the attached roadworthy certificate sent to me ASAP, I also need to know when am I getting the spare key.
