Telkom service is appauling !!!!

I had taken out a LTE contract with Telkom in June last year for the unlimited data. To date, I have not had reception to pick up the network. I have requested to cancel this contract, send through all the documents and still Telkom debits my account. I had spoken to Lungile who advised that I would not be liable for any penaulty fees and that all the premium paid would be refunded and I am still being debited R600 a month. This is totally unacceptable. I have had a number reference numbers closed as they say that consultants have not been able to get a hold of me. My new reference number is ***1. PLEASE CAN SOMEONE IN TELKOM SORT THIS OUT !!!!
