disgusting services

i have been speaking to multiple agents for the past 3 weeks trying to sort out my account as I am being billed triple the amount I am suppose to , I am then promised escalations from multiple dstv agents named mufaila and tshepo but up until this day have jot received any call from there contracts department , as I have the explora price lock plan. this is disgusting services always having to be on the live chat with no luck in getting my issue resolved. dstv then also did not want to upgrade my plan to the premium package as they say they cant do it only the contracts department can, I then ask them the number for that department but been told I cannot call them as they are only outbound call centre , the service I have been getting is disgusting and I have emails of the proof as well as to what they have told me and promised me call back within 72hrs and yet still nothing ..
