VODACOM ACCOUNT NOT REFUNDED

I am SO SO unhappy with VODACOM and so frustrated!!!! I have a problem with my account since MAY 2020 and it is not resolved as yet! In the mean time, my account keeps on accumulating and I am kept responsible for the outstanding amounts. Purchases were made accidentally on my Vodacom account. I immediately contacted the Company, and got assistance right away. I have PROOF of refunds, Tax Invoices etc received. I visited my Vodacom Branch in Northcliff with all the REFUNDED EVIDENCE, and still they directed me to call 082 135. COULD NOT ASSIST ME! I called 10 000 times, visited my Branch, sent emails to everybody I could find on the Net. This includes EVERYBODY, and I meand EVERYBODY!! From the Secretary of Vodacom right through to the Complaints Department with Telecommunications ets. I've completed a Complaints Form, sent ALL Tax Invoices, Proof of Refunds that was done to VODACOM, and still NO ANSWERS or corrections of my account!!!! It feels like I'm running into walls and there is NO ONE out there that can assist me. What MORE proof do you need other than the PRINTED evidence that these amounts must be credited back to my account!! I will continue to sent emails, make phone calls, visit my Branch in Northcliff, keep on harrassing people out there until my problem is resolved! You can't "chat" to the assistances online, as they are always busy. (I have actual screenshots on how many times I've tried that path). NO PREVAIL!!!!!! Vodacom is not willing to assist their customers in ANY way. ALWAYS ALWAYS excuses! I've asked on several emails, phone calls etc for Itemised Billings with regards to the months in question. I AM STILL WAITING........DO THEY HAVE SOMETHING TO HIDE????????????????????????????????????????
