Shocking service in resolving and crediting ********** cellphone charges deducted on my Edgars account.

Cell C have been fradulently deducting airtime and mobile vault charges on my Edgars account since March 2020. After countless emails and calls since July this year, including an escalation to the manager of the ***** division, Tebogo, and various follow-up emails and phone calls, I'm still struggling to get the money back that they charged on my Edgars account. Now - after all these months, they only refunded about 25%, and require me to submit 18 months of statements to them to prove the debit on my credit account (that THEY charged to my account) before they will refund me. Their service has been exceptionally poor, especially considering that this is a matter of *****, and the escalations that I've done to resolve this to date.
