Revolting Service!!!!

On the 22nd May 2015, I contacted Capfin to request for a settlement amount. <br> My debit order had gone off and I advised the agent to include the debit order amount in the settlement amount as I wanted to pay in the round figure. The agent advised me that this has been done and on the 25th May I made the payment and received a confirmation on the 26th May that my account has been pay off and that I was due for a refund. The refund was done on the 27th May. A week later I received an sms stating that my account is in arrears by R950.00. This amount has been accumulating and now it is sitting on R3845.06. Now my question is that how can they confirm that the account has been paid up and then start sending me sms' stating that im in arrears. My name has been dragged into the dirt because of Capfin who is not even sure of their facts. I have asked for voice recordings for the call that I made requesting for my settlement amount as im sure that I mentioned my debit order being included and I haven't received anything, someone in collections promised to contact me so he can play the recording and nothing has been done, however the amount keeps accumulating. What ******* service is this?
