****ed off

I so disappointed in FNB, im trying to access my revolving loan with them just to find i cannot cause apparently my overdraft was in excess for in September and October which i have not known about, but i got paid on 25 and 26 and made payment with my salary for accounts so my account never shown me that i was on minus figure in my app, i get paid twice a month and I pay hectic bank charges and i have my business account with them and numerous vehicles finances, i feel i need to be move all my assets away to a different bank if i cannot be assisted, I've been with more than 15 years
