BAD SERVICE - ACCOUNTS UPDATE

I'm so upset with the service of Rcs - Game . After my debit order didn't go off I've made a payment at the store but since they can never tell you your amount due i paid a R80 short & received a sms that no installment was paid 3 days there after . I immediately contacted their service centre to enquire & made all the necessary arrangements & set new debit date to correct bank account . Everyday since that arrangement i still receive up to 3 calls everyday from different consultant to enquire on my outstanding account this is not professional at all!!! It tells me that they have absolutely no process in place for their consultant to check updates or just feel to intimidate their clients!!! . PLEASE DO PROPER CUSTOMER SERVICE BECAUSE AT THE MOMENT YOU SUCK AT IT !! I'm not one of those client's that intentionally won't pay my account's "I've approach the office as soon as I saw the mistake to arrange that the payment gets updated "
