unhappy customer DSTV

My dstv account was deactivated on the 27th of june but I had already paid for the month of june and I called in by your call center on the 29th of june the matter was resolved my dstv account was activated again. this past weekend on the 5th of july I made another payment for the month of july. Then on monday the 6th of july was deactivated and I went to one of you dstv agencies and they told me to pay reconnection fees wich I did and it was activated again. This morning when I woke up my account was deactivated again. I called through to your call center this morning they told me that two payments were reversed. So how could I have reversed the money if I make cash payments its not like you debit the money from my account so I couldn't have made any reversals or disputes as I always make cash payments. So can you kindly sort this matter out my card number is ***.
