Online Banking Blocked

I cannot log onto their Internet Banking,because they say \unpaid suspension\" as the administration fee of R5.50 for January was not paid. In fact there has always been at least R1000 in that account. In spite of five phone calls to *** and two promises to phone me back, the problem persists. They send me dozens of SMS's but couldn't be bothered to tell me their problems about this. One Call Center reference was C***. Why do they punish me like this???"
