Makro and the poor customer service

This is ongoing from previous reviews. There was a payment made by myself 9th September, thinking it would be covering September installment on my Makro account card. Makro card ( RCS ) chose to take the amount as an extra payment for August before closing off their month of August. On 9th September I received an sms to make payment by 12th or i would be handed over to collections. I contacted the number given in the sms and was told that statement process date is 12th and therefor they cannot reflect my payment as September but extra for August. After my previous reviews, I was contacted by Cindy on 14th October and assured that the matter has been resolved. After the call up until early hours of the next morning I was bombarded with old statements dating back to November 2019. There were messages which still indicated that i am now in arrears. The final statement I received was the September 2020 one still indicating arrears. I contacted the call centre and got through to Mandy who again confirmed that my account has been fixed and she sent a query to accounts for an update. The confirmed installment amount was said R898. On 17th October I received a statement again showing arrears and an installment due. What are the staff actually trained to do? Why is it so important to just have their company name removed from the reviews and lie to get there?
