Unhappy client

I made a purchase at Hungry Lion PAROW Centre and the payment didn't go through according to them and on my account the payment went through and I told the manager in PAROW instead she gave me an attitude and now in order for me to be assisted I need to waste my money and go back to the branch and that is gonna inconvenience me and I will have to use my money to get my money back.

Capitec Bank advised me that I will need to get a letter from you guys with all the below details.

In order to reverse it you will need to provide us either with a decline slip or a authorization letter provided by merchant. Kindly note that you will need to contact the merchant directly and obtain said letter from them directly. Kindly note that the below info is needed on the authorization letter: -Company letter head. -Date and amount of transaction. -Confirm the last 4 digits of card number used. -Letter needs to clearly state that the merchant in question gives us as your bank permission to reverse the funds. -Signed by appropriate manager/parties involved. Purchase Not Processed +R179.80; Ref HUNGRY LION PAROW CENT on 29-MAR. Merchant may process purchase in future.

I need assistance ASAP and I ain't going back to PAROW centre and I need my money please help ASAP
