Telkom Archaic business practices

I canceled three accounts on the 21st November 2014 before going overseas for work. I got SMBS retention emails from felkom acknowledging receipt of these cancelations. Telkom however carried on charging, and after raising a dispute on these accounts, have refunded me on one account only. One is under investigation still while the other one has been rejected with no valid reason given. When I asked the consultant, she says they don't have a reason.<br> Why if all three where identical in nature and only the numbers changed?? Seems telkom is run by 5 year olds. Please can someone that knows how to sort this out call me ?????<br>
