Absolute lack of interest in business clients (unable to open general trust account)

I am an existing customer and completed a form online several months ago to open a general trust account with FNB.

I received a reference number and a promise that I would be phoned.

I phoned the FNB Business Desk today and was promised that the person dealing with trust accounts would phone me immediately.

Again, no one phoned. What do I have to do to get any service?
