Poor service

I've been a customer of DStv since 1995. I cannot believe the poor service from the call centre. I have requested and left messages for the team leaders but no one ever calls. I ask to speak to a manager they blatantly refuse to let me speak to one. Money gets paid for box office and you cannot view the movies after 10 calls to the call centre and them telling me they will call me back I have still not had any contact from them from 24 December 2021. I cannot understand how *********** the staff is at DStv. I'm at my wits end and don't know how else to sort this out.
