********/ ********** behaviour in not refunding customer

Telkom has debited my account for a new product that I app**** for. It was a month to month SIM only LTE deal. They then cancelled my order without informing me or refunding me. When I phoned Sales to asked what was going on they said they couldn't help me and referred me to Order Progress. I have no order number. Order progress informed me that my order was cancelled by Telkom and that I would be getting a refund in 3 days. This was on the 19th of February. I have still not received my funds. I phone Telkom every week and they "escalate" the matter but nothing happens. I cannot speak to any other department, or anyone in management - because of the "work from home" excuse]. Even 4 requests for callbacks by management have never been responded to. Finally last week someone tells me that it was going to take 21 days instead of 72 hours. 21 days from when? The only thing I have to prove I even exist is a case number and my bank statement. Finally today I phone Order Progress and they send me to Billing [after 6 calls!!??!] (even though I have no order number & no product). Billing then sends me "Mobile Billing" who give me a new case number and tell me to follow up in 3 days because they believe I should be given a refund. I now have at least that new case number and at least some department at Telkom believes in my refund.
