Interest Charged on Zero Balance

My guestion is, I went to Makro, I pulled a full outstanding slip from the Teller and paid the full amount, no outstanding balance, I went to Game half an hour later and did the exact same thing however I get charged interest on a zero amount, When I called in to the RSC group, I was told but you requested a settlement on Makro…. I did the exact same thing at Game so how does that work?

On Friday I called Game and got a settlement amount from Tashmien of R96.38 and made the payment immediately. Today i get a mail from Ndilleka that my outstanding balance is R96.54. Just a break down of these orignal charges that got me up in arms i must add comes to the following R0.89interest, R4.00 Customer insurance R91.29 interest on a statement send on the 11 of february, interest and customer insurance on what, on an account that was settled on the 4th already? You cannot charge interest on interest on an account that has an absolute zero balance!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! That was paid in full in store!!! No where but no where does it state in your terms and conditions does it show that I have to pick up a phone and call the headoffice to get a settlement amount, so going into the store, and requesting a settlement amount from your accounting system at the teller is exactly the same thing!!!!! Proof of that is in the fact that my Macro account does not have a cent outstanding however the game account does after both of them was paid in exactly the same way, Your Terms and conditions states and I quote “ if you wish to settle your account, you must first contact us to obtain a settlement amount” Going into your store and requesting a settlement amount is exactly that!!!

Game: Clearwater Mall Balance Requested at 09:08 on the 4-02-2018 Current Balance R6490.86 payment Made 09:09 of R6490.86 Makro : Stubens vally Balance Requested at 10:58 on the 04-02-2018 Current Balance R12929.91 payment made 11:00 or R12929.91

As well as having to hold on for 25 minutes or more, just to be able to close both accounts is total Ludicrous and I am at my total with ends with RCS now!!
