Incorrect billing.

I moved from dstv access to compact. In January in feb8i received a message from that I owe 891. I inquire at you call center they said they will escalate my call to your accounts department and their will call me back which they never did I paid 500 end February until the issue was sorted. I further enquire from your dstv of Facebook which they advise me that the billing was incorrect I had to pay 197 to keep my services active. I paid 200 today. But when I checked again it's still showing that I owe 691. Someone needs to sort this out. I don't know what ****** business is going on there or what are you cooking in my account if this is not sorted out by Friday u can kiss the services I pay for goodbye. This is ****. I'm very ****ed of
