Most unreliable customer service on accounts!!! Don't fall victim to these money sharks

I have been battling since 3 August 2022 to give notice on my wifi contract that expired end of August 2022. Multiple emails send and received with reference numbers etc. Finally got through to an Agent to talk over the phone, but the moment he heard the word cancellation, he could not hear me anymore, apparently my line was breaking up although i could hear him clearly. Went into a Telkom store on Friday 4 November to sort the issue that Telkom deducted almost R1700 from my account 28 October. Instore they could not help me, because my account has been suspended for the almost R1700 outstanding that was deducted. The lady logged a call back on her system for someone from accounts to phone me - today 7 November @ 11h00 I am still waiting for the call back. YOU WILL NOT DEDUCT A CENT FURTHER OFF MY ACCOUNT.
