do not respond for error resolution

MUltichoice/DSTV will bill prorata if account not paid, however after account paid we are not able to view the 3rd tv channel,<br> <br> Call centre cannot resolve error and problem escalated to technical who would respond within 24 hours, This happened early December , still not response, Yesterday (21 December 2015) called again and call escalated for a second time, still no response today 22 December 2015. called again and now escalated a third time with agent hoping that call will be addressed within an hour. DSTV however don't seem to repay (prorata) the fee billed for the unusable third viewing channel. DSTV customer service option after a call does not have any options for dis-satisfaction with company, only options are for agent analysis.
