FNB - how can we pass the buck for you?

For over a month I have been trying to finalise a secondary user profile for my colleague, on my business banking. After several weeks and to-ing and fro-ing to get the correct paperwork, I finally got the secondary user profile - only to discover that they claim the secondary user can't access the USD account! I have phoned and mailed (at least 4 staff members) - and NOTHING. No replies at all - when they were replying they ALL passed the buck. I requested a meeting and was refused. It's always someone else's department - this just CANNOT GO ON. Do they want clients? I am happy to put the names of these staff on Hello Peter, but hope that someone at FNB can actually assist. I refuse to waste more time on the phone and resending MANY emails.

HELP!!!!
