Standard Bank FICA system problem

Further to my complaint dated 30 March-nothing has been resolved, nobody is getting back to me with anything concrete other than empty promises to follow up. Apparently there is a nationwide system problem causing clients' accounts to be inaccessible. I have been unable to access my credit card account for over a month now. Despite numerous mails (daily/every other day), the only response is they have escalated and will get back to me. Which doesn't happen. I seriously question the competence of an IT Dept which cannot resolve a problem within a month. I seriously question the lack of customer service. I am receiving no feedback whatsoever and sense a distinct \do not care"attitude. Now i receive an sms stating my account is overdue"
