******* Debits

Telkom is *******ly debiting incorrect monthly payments, I took a contract of R303 and now they debiting R820 every month, I kept going to telkom branches to fix this and I was promised that it is fixed but they still debiting. I am calling to get it fixed but they keep hanging up the phone. OMG what should I do to get help and cancel this incorrect debits this is so depressing. Telkom can really **** a persons soul
