DSTV Refund delays

Multi choice (DSTV) N1 city has a poor poor poor customer service, we have been back and forth 13 times to resolve a refund issue, giving us the run around, every time having to re-explain the issue to a different sales person after about a 40min waiting period... im not sure what the chain of command is there but our issue is something that the sales agents cannot resolve, its highly frustrating to even have to wait on a supervisor on every occaison, then finally when a supervisor assists us that said supervisor has now changed employment and now we back at the begining because nobody took over her querries and mails... its such a task when they have to pay you back having you jump through loops and hoops like a circus... but when the shoe is on the other foot they demand payment. My issue is still not resolved after months
