RCS game store card incompetence leading to bad credit record

Lack of communication leading to bad credit record, unacceptable. I over paid with 12k in September, no sms statement came through before my pay date as per usual for the mothend of October, so i paid half of what i usually pay R1000. No sms or email to say i have short paid. Suddenly today i recieve a sms and a call from a very rude lady saying im overdue for R2044. She couldn't even explain how, she hung up. I called back and spoke to Karen @3h50pm, she also had to refer to her team leader Joelene who had to escalate or something to i dont know who for what. In short, i requested a cash advance of R1500 yesterday on my App, that was not blocked or showing any arrears and it was approved and the message said 24hours i will recieve the funds. I am still waiting. Ive never missed a payment, the smses guide me how to pay. I am not happy with the service at this point and i want that cash advance ASAP. Them not updating in time is not my problem.
