FNB CLIENT TO LEAVE TO THE BIG BLUE BANK!

I have been with FNB for years have 2 home loans with them. I have an access account and they just deactivated my access on my bond without even a call. I normally like to add extra money into my home loan, this now avoids me adding extra money and I am talking to another bank to switch my home loans to go to the other bank cause this is uncalled for , especially when I never missed a payment and a good payer and have 2 home loans with them!
