43 years of business banking isn't entitled to much customer service from FNB

I’ve just bought a business thats been running for the past 40 years. For the transition- the previous owner needs to keep their bank account open, and she and I need another business account opened for the way forward. Our FNB business banker for this business has promised to call back and work things out, but to date (almost 2 weeks later) nothing from her.

It’s gotten to a point where FNB is making it so hard to keep the business with them that it’s on us to open another bank account for the business with another business bank. Do you think we will consider coming back to FNB after getting that right? I don’t think so… but that doesn’t seem to be affecting FNB- who seems happy to lose a business client that they have had for the past 43 years
