Vodacom not Paying Refund.

So I over paid my account at Vodacom, I paid manually and 2 days later they debited me. I informed them the next day the 26/04 /2022 the agent told me to send email to *** with proof of payment so that i can be refunded, sent it but they told me they couldn't get it till i received a direct email and it was sent. On the 30/04 /2022 Vodacom informed me that they got confirmation from my bank as proof of payments. I resent pop again as per requests 3 or 4 times. Long story short to day is the 17/05/2022 no refund from Vodacom no one knows why they all promise to call back they cut calls asvi ask whyvam i not getting my refund. I even went to the Hillcrest store KZN i was told there nothing they can do. Basically i have been ******. Even their Twitter account is useless no management tried to contact me I've been caing them daily for over a week now. Vodacom is going down the drain with these call centers. Sad coz they will debit me again next month but they stull owe me i feel ****ed.
