Pathetic Telkom customer service

I have cancelled my Telkom line *** in JULY 2018. Reguest number ***0. I contacted the Telkom Service Centre and they confirmed that the final account will be issued at the end of August. Up to date I am still receiving accounts. I contacted Pumeza on Tuesday 23 October 2018, reference ***. She logged a dispute on reference ***9 to reverse charges. Nothing happened. On 2018/11/30 I spoke to Chante. She logged 3 x disputes to cancel the 3 notification charges. Then she reversed the charges herself. She said I will receive another final account with a credit which Telkom will refund me. She did not issue a reference and said I will receive messages via cell and I can use her name as reference. I received a final account in December 2018 with an amount of -R1,383.34 owed to me. I contacted Telkom on 2019-07-12 and they told me no final account was issued. Busishwa will send an email for final billing account. She cofirmed that she has by banking details to refund me. On 2019-07-24, spoke to Xolani. He told me that he will request another final bill. He will email a person with the name of Bongani to notify him that final payment has been issued. Xolani will request that Bongani confirm with me via email. I received a phone call from Annelien on 2019-07-24. She told me that the final payment due to me will be made within 5-7 days. Up to date nothing has been paid into my bank account.
