Disappointing service from Telkom to process Refund

Hello. I am so frustrated with the service I get from Telkom. I had an issue with my account last year August-September 2020.i have made numerous calls to Telkom and received 2 case numbers along the way. Today I followed up with my refund, the lady I spoke to said there was no record of my case numbers and that she would log a case for a refund and that I would receive an sms after call with the case number. I have no received that sms as yet. I am furious that all my calls stress has been for nothing. I have also sent emails to a supervisor and a call centre consultant that promised to resolve my refund request. There was evidence that I was incorrectly debited for 2 contracts that were already cancelled. They also agreed that there was an error. I don't understand why it's taking so many emails calls with no resolution. Someone needs to investigate what happens to all the calls we make for complaints. My old case number was ***3.new case number was ***3. People I emailed with absolutely no reply to my many mails. *** and *** I deserve I proper explanation why all my comms have no been recorded and why no one has been able to refund my money. Telkom owes me R856 for 2 cancelled contracts subs but who will refund me for at least 10 calls and 4 emails pleading for assistance. I am disappointed beyond words.
