Poor service from FNB Enterprise banking.

I have opened 2 accounts for 2 separate NPO's with FNB. The accounts were opened quickly, but I have been waiting for more than a month for the enterprise banker to link the one account and 3weeks for the other. We were promised contact within 7 days. Every time I query I am promised that it will be escalated to a manager and then I receive a ticket that they have 3 days to respond. In the mean time our electricity of the buildings risk being disconnected. I have never received such poor service from a bank. Last time ever.
