Expired temporary license and no help

I bought and collected a car from Fury Mazda in Midrand on Saturday 17 October. Calvin Nkomo, the salesperson, told me that I should be getting my number plate and license disk the very next week. <br> <br> It is now almost 4 weeks later and I still haven't got anything from Mazda Midrand. I have tried to get Calvin to do something about it but he keeps on giving me the run around by not responding to emails, not returning my calls or the one time I did get hold of him, he made a promise he didn't keep. <br> <br> The main problem is that the temporary license expired on 6 November. So now I have that I can't drive. <br> <br> Can someone please get this sorted out.
