RCS - Worst Experience Ever!

I decided to apply for an RCS card and was successful at obtaining one. The trouble however started with my first payment due in April 2015. I made a direct EFT payment on the 28/04/2015 of R600, a day later I had a further R597 deducted via debit order from my bank account. I contacted the RCS call centre and was advised that I should contact my bank and reverse the debit order as I had already made a EFT payment the day prior. In May 2015 I then received my updated statement which showed that my account was in arrears, I immediately contacted the RCS call centre only to be advised that the R600 I had paid had not reflected on my account, going back to my proof of payment I noticed that I had put 4 digits short at the end of my reference number and therefore the money had not been allocated to my account. Since having sent through my proof of payment 3 times and numerous calls to the call centre I have been shoved from pillar to post, I was assured last week Tuesday that my account would be rectified and the money allocated but after phoning through yet again today I have come to be informed that my account is still not up to date and the R600 payment has still not been allocate.
