Another unhappy FNB client!

I have had several FNB accounts for at least 15 years and always had 4 debit cards linked to my business account, as this has been vital in how I run my business account. With one of the cards expiring at end of January, I have been told by FNB that because they have changed their systems, I can no long have 4 cards linked to the business account - the maximum I can have is 3 cards. This doesn't work for me as I need 4 cards. It may be time for me to look at other bank offerings, if they can make it easier to run a business account the way that works for the business and not dictated to by FNB!
