DSTV Incompetence

In february 2018, I requested for DSTV to disconnect,when this happened I had a credit balance with them, it was suggested that i will use this when I reconnect. in December 2018 I called in to be reconnected, they reconnected, then they said they will transfer the funds from the price lock account to the residential one, however every 3 days, they disconnect me, I have to call in to get reconnected and when this happens every time I get charged R60 re connection fee, so far I have called in more than 9 times with the same issue, each time they person apologies, reconnects, and says she will escalate for the funds to be transferred, to this day since beginning of Dec this has not been done, as I type this, I have been disconnected once again. This has become a nuisance, like airtime is not free. Because of this, I want a complete disconnect, to stop using DSTV and my credit balance be paid back to my bank, I honestly cant be going back and forth over such trivial things, I can be going for 2 months with the same issue
