No response from Nedbank query

I requested statements for my Nedbank credit card on 3 March when I realised that I would need them for a SARS audit on my 2014 tax. They said it would take 48 hours. I phoned again on 6 March who said that it was on the system but they could not help as it was with the \Back Office". Still nothing. I phoned again yesterday 9 March. They still have not started to deal with my query. SARS give us a 5 day period to resolve the audit queries. I have sent a complaint on the Nedbank website. There has been no response. Nedbank do not care about their customers. """
