private banking

My profile is blocked and I now don't have access to the app or fnb online. I'm currently out of the country and can't go to a fnb branch or go to a south african embassy. I spoke to my private banker and he has been of no help. He doesn't even respond to my calls or messages . I've been waiting for him to assist me since Monday. I'm out of the country and he's not helping in any way. I desperately need access to my account, I have bills to pay and I can't do any of that. I can't even activate my new bank card. I'm stranded in another country and fnb can't do anything to help. It's very frustrating.
