Absolutely PATHETIC customer service

Telkom On the 6th of May of this year I cancelled my Telkom account. This process took Telkom more than 3 months to sort out. They just continued billing me for a service I have cancelled, which they also responded to by saying they received my cancellation request. I went through the cancellation process more than 9 times during this 3 month process. Every month Telkom still sent me a bill. They eventually handed me over to their attorneys as a bad payer. I made contact with their attorneys, and sent them all the documentation and correspondence, but still no luck. Eventually I had to pay a massive amount to Telkom just to ensure that the attorneys don't list me as a bad payer. Eventually got my service cancelled, then had to file a dispute with Telkom to get my refund of the money I paid. Now I want my refund, and Telkom cannot do this as they want a bank stamped bank statement. Even though they have my banking details on record for the debit order they have successfully deducted money from for more than 3 years without fault.I am not a social media complainer, but this is ridiculous!! Your call center is useless, your web chat service is useless, Telkom in general is useless!! I expect someone to please make contact with me ASAP and arrange that my money be refunded ASAP. I will gladly post ALL correspondence of the past 6 months online for all to see the glaringly obvious disregard to customer service and the incompetence level of ALL the staff I dealt with should someone not make contact with me.
