FNB impossible to reach the right department, they gave me the wrong phone numbers!

Once again I find myself unbelievably ****ed off and irritated with the elaborate maze of communication and incorrect phone numbers that I have to navigate to get an answer out of FNB. All I want to do is know why my revolving loan facility is no longer available despite it having been paid. I have been phoning all morning and given the wrong department's phone number by all manner of different departments. Will the correct department please phone me and give me the answer to my question! This is why I downgraded from Premier Banking to Gold. Why pay all that money when you take forever just to answer one question and it's never the right department!
