FNB at it again

Another round of extremely poor service from this bank. More broken promises and failure to complete basic tasks. I have been with this bank for many years and despite many attempts and phone calls to resolve my issue, which they have caused, my account is now locked out. How can an organisation of this size constantly get it so wrong or am I just very unlucky? An example of another big corporation that does not care about it's clients! Supposedly all calls are recorded but obviously not monitored, as surely someone would not let this kind of nonsense continue. Does anyone know of a bank that actually gives good service? Would never recommend this bank to anyone.
