Frustrating upgrade experience

I've been trying to upgrade my Gold cheque account & credit card to Premier however no one at FNB is assisting.

Secure chat puts me through to Private, who transferred me to Premier, who transferred me to Sales, who transferred me to Gold.

When I try calling ***, I get put through to Private and get stuck in the same never ending loop.

Very often the calls seem to "drop" or is just being cut by the FNB Banker.

This is a very frustrating experience, please can it be arranged for the correct team, to effect the upgrade from Gold to Premier, to contact me.
