Still no response from Multichoice

I called Multichoice about my faulty dstv installation and was promised that they would respond within 24 hours. Ref no given 1486. I am still waiting for the call. I am very upset - I have paid my subs for dstv for the month but my dstv hasn't worked since the 1st of December. I might just as well disconnect it permanently. The installer that was sent to me is *********** and I already had to pay him R 350 to fix the ****py installation and its not even 3 months since he came, now the installation is faulty again. I'm done with this company.
