Scheduled payments and transfers is on FNB's website is a broken mess!!!

FNB's website is very buggy. For 3 months in a row they have messed up my scheduled payments and transfers. Two months in a row my scheduled payments went off twice for no reason causing my account to go into overdraft and then they would even billed me for the overdraft usage. For the last 3 months my scheduled payments have gone off only to be notified a week later that the transaction has failed.. All of these scheduled payments and transfers have been set up for over a year. I am having serious doubts whether or not it is my money is even save at FNB.
