RCS game stores

I paid my account via eft the 28 August it's the 11th of October... My payment has not been allocated to my account... Every week I'm calling the call centre just for them to say they will allocate my payment accordingly. This has negatively affected my credit record. As they have listed me as a non payer in return i had to make a double payment for this clear the account. Up until today no communication from them.
