Dstv

I am so dissappointed with DSTV and the wrong billing on my account that no one can even explain what is going on. I have won a free upgrade on the wheel of happiness in April and bow its like they want nme to pay back the subscription. They have been some reversed transactions on my account that I do not understand and does not show on my bank statement because they say i have reversed the payment which i did not. So my account balance is very high this month and they are even reminding me the debit date. How do i solve this guys.
