Disgusting service

I have recently been listed by Nedbank apparently I am 9 months over due on an loan account. Problem is I have not opened any accounts in years. I tried calling Nedbank customer service yesterday and after 2h30min still no resolution I was transfered from department to department and no1 could tell me what was going on. Then I left a message at about 10 yesterday morning for some1 to call me and nothing. I the called again at 4:30 and nothing still no call back and still no solution. Is this the brilliant service Nedbank always goes on about. From my ex Nedbank customer service is a joke. They don't know what's going on and all they can do is waste your time.
