Rcs is useless

RCS PUT MY ACCOUNT ON HOLD FOR NO APPARENT REASON, MY ACCOUNT HAS NEVER BEEN IN ARREARS, FEES WENT OFF AND ACCOUNT WENT INTO A MINUS NOW THEY STATE THAT I HAVE OVER USED/OVER DRAWN THE ACCOUNT!! I PAID THE ACCOUNT IN FULL WHICH WOULD ALLOW ME TO HAVE AN AVAILABLE BALANCE AND TODAY THEY SAY THAT IT HAS BEEN OVERUSED WITH R700 and the first guy said 500 before I MADE A PAYMENT!!!

I REFUSE TO PAY FOR SOMETHINF AND NOT BE ABLE TO USE IT!!

PLEASE GET SOMEONE TO CALL ME BACK ASAP BECAUSE I'M SICK AND TIRED OF THIS!
