No Service

I went the 6th of Jan 2017 to the Mercedes Branch in Menlyn. I asked the salesman that I want to purchase a Smart for Two vehicle and that he must get all the paperwork ready for this transaction. The Monday afternoon after not hearing back from him I phoned him to ask when the process will start whereby he rep**** that he will be getting a demo Smart in the next day for me to test drive. Tuesday afternoon I contacted him again whereby he rep**** that he was still waiting for the demo. I asked my husband to go in to the branch to tell him that I want to purchase this vehicle and we must start with the paperwork because it looks like this salesman does not understand what I want. Since then and from the beginning this guy never phoned us back or give us any feedback. I do not know if it is because we did not buy an expensive vehicle or what but surely we are also customers?
