my account is closed with payments uptodate

I made an EFT payment end of July and they told me it does not reflect so I made a cash payment beginning of August 2015 whilst I sent them proof of payment ***. I was informed this would take 21 days however in the interim I have made cash payments every month for my subscription but every month my account is cut off and they have different reports of me owing them money and when I call them they find all my payments and reconnect but the following week it's disconnected and every week there after this has dragged on from August 2015 till today 20 November 2015. This week my account has been off the entire week and I'm told there was a debit order linked to my account of which I was paying cash ever since I bought this decoder. I recently found out that the debit order was of a school account which does not even have Dstv account. Now the 21 days are long over no one has ever compacted me for the days my account is off and the people checking this account all do not want to call me and give me an explanation why my account is still off and why my extra payment is still not allocated after sending proof of payment numerous times. I have all emails and tweets. ***
