BAD "service" changes without notification...now I can't transact

This is absolute nonsense !! I have been banking with FNB for the beter part of 25 years. I'm closing all my accounts. I had to make payments today just to get a msg that I now suddenly after my business account has been open for 7 years have to have a card and that I am now limited to the amount that I can transfer or pay ?? No notification or messages just sorry...you can not pay your bills today why now ?I'm and forget 'bout phoning or their 'chat it's an dark hole where one guy points you to another... This is BAD....I'm moving all my banking to Investec !
