Still billing me- I am on prepaid

To whom it concern,<br> <br> I have just received a call from your call centre ***). According to your call centre agent, I still owe your company R117. Please go through my previous complaints on Hello Peter. The complaints state that I have been receiving these types of calls from your company even though I have paid the numerous cancellation fees that your company has been charging me. <br> The head of your customer complaints called me and confirmed on numerous occasions that the issue had been resolved and I even received a credit from Autopage. <br> I am no longer an Autopage client (thank goodness) and am on prepaid with MTN. Why am I still being billed R117? <br> The last correspondence between Autopage and myself was in May 2015. Please investigate further as this is ridiculous. I have complained numerous times on Hello Peter about this issue with Autopage. Please go through my previous complaints and resolve this ASAP. Your company is treating me unfairly. I have lost faith in your business. This has been a nightmare.
