Online Banking Profile Blocked

I'm travelling overseas and yesterday I suddenly found out my FNB log-in details are not longer valid. I can't log into my online banking either on my computer or on my cell phone. The call centre says it's a business profile and personal profile migration issue. Escalated the issue RR***. But no one is getting back to me. I have forex deals I need to execute urgently or I'll face large penalty. PLEASE, unblock my profile. I'm overseas. cellphone doesn't work. but you can contact me on +*** or email me.
