Refund on my account

I ATTEMPTED to make a purchase from my local Checkers store on 9 May. I called the same day to check what happened and was assured that although the amount reflects as paid from my account it has not been paid over to Checkers. 2 weeks later and I noticed that amount was still reflecting on my account statement. I went back to Checkers and the account manager called your call center form the store, I sent 15 miutes on the line with an advisor and was again assured that this will be reversed to my account. Checkers have included me on emails sent to your head office showing that the amount has never been paid to them from RCS. Now more than 2 months (47 working days) later I still see NO reversal on my account from you for the amount that I paid cash for. I am being charged interest on an amount that should never have been processed through my account. I want this sorted out by close of business tomorrow and I expect to see a new statement showing this amount was refunded and the interest you have charged me the past 3 payment runs is included. Account number: *** Purchase date: 9 May 2019 Location: Checkers Raslouw Amount: R 358.19
