Pathetic Telkom Service delivery

What pathetic services i have been receiving from TELKOM! Calls would get cut in the middle of conversations, and it would seem that TELKOM employees just do not understand a very simple request. The right hand doesnt know what the left hand is doing. I cancelled a contract in June, effective from July 2021 (way in advance to allow TELKOM enough time to reconcile their books) and yet they continue billing and debiting me for the contract despite the fact that i have a cancellation reference number and many case numbers due to the all the calls I have been making - but these apparently mean nothing. I have called numerous times - consultants would acknowledge that they can see the cancellation request on system however, I am not due a refund. C'mon TELKOM - it makes mathematical and accounting sense firstly, TO NOT CONTINUE BILLING the client and TO REFUND the client for debits made on the bank account. How difficult can this be.. certainly NOT rocket science. I have a plathora of reference numbers and unhonoured commitments that a manager would contact me, or that my case would be escalated - however i am still battling to get refunded the amounts that Telkom billed me for August and September 2021. What a disgruntling experience it is to be a TELKOM customer... I am disgusted!
