Still not resolved - VODACOM IS AWFUL

Still awaiting a call from Vodacom!!! On the 1st April 2022 at 08h06 (please pull the voice recordings) I called and cancelled ********** (contract ended end May 2022). However I was billed in June and now again in July for the contract even though cancelled and confirmed on the voice call that I called in the 1st April to cancel but the person DID NOT CANCEL - it is now cancelled. However Vodacom continued to take payments on a cancelled contract Credit due back to me is: June R188.37 (already deducted and paid) July R188.37 (already deducted and paid) Total: R376.74

As per my August statement no credit is showing against the number that where is my credit and please advise how I get it refunded into my bank account

This is why people like my cancelled ALL MY VODACOM CONTRACTS YOUR SERVICE IS TERRIBLE ABOUT BEING A LOYAL CUSTOMER FOR 20 YEARS
