Solved but still receiving request for payments?

We loaded a complaint on 20/1/2015: Telkom Centurion breached contract and we then proceeded to cancel contract in January 2014. After several phone calls, emails and visits they are still unable to solve this problem and keep on deducting funds from our account and don't respond to communication. <br> <br> Still not solved and not sending emails as promised in order to refund bank charges. Also still receiving messages to make payment? How can this be solved if we still receive messages to pay? Almost a month after complaint was done on Hellopeter and still unable to receive assistance.
