Worst Service by Service Provider - Winner PayCity

I have now been waiting 4 months for my License disk after payment was made. I have phoned 7 times and every time I get a different answer and the administrator Ashley Jacobs will phone me, to date not one call not even from the manager Daniel Bopape who i also asked to phone me to resolve. In the mean time I have been pulled over numerous times and had to explain why i am driving around without my renewed license disk. This is the worst service I have ever seen. They encourage users to use the website, just does not help if there is no process supporting this.... What should I do?
