FNB Online Banking Inefficiency

I can understand why there are delays with reference to high call volumes for the online banking call centre - the service is so poor that calls take forever! FNB (Three Rivers) gave up on trying to solve an online banking problem that I have (Error E-5509) and no-one can help me and I cannot get hold of the Help Centre. I am on the brink of closing the account and placing my money with the bank next-door (Nedbank) who seem to value my status as a small-business.
