FNB blocked all my accounts while abroad without notification its been weeks and many emails

I am abroad and FNB blocked my access to all my accounts without giving me any notice. It's been weeks with continues demands for various documentation to be completed to get access to my accounts online. I think it is such bad service to do that to a client without any notification. It has been weeks and I still have no access after its been stated all is in order and it will be resolved. Yet still no access. Can these people not understand that if you are abroad you can not go to an FNB ATM and verify your account as they request on the FNB site. Please people wake up.
