Worst service experience with Multichoice

I have been battling for two weeks with Multichoice. I have app**** for an upgrade to Ultra decoder and my first frustration was was that contrary to my experience with Multichoice I had to wait for two hours at their offices in Randburg before we could be attended. Secondly, I was promised installation of the new decoder would be done within 7-14 days. To date we have not even received a call from an installer besides numerous promises of escalation of my case. This is the same Multichoice which cuts services as soon as monthly payment date passes without pay.
