Forex Payment, ARN number

I am at my wit's end with this bank, I received money from my broker, 2 months ago, from overseas along with an ARN number to prove that money has been sent to my FNB account. Yet FNB lacks people with an understanding to deal with this type of situation. To this day they cannot assist me. They simply plead ignorance and direct me to someone else who does the same.

Noone seems to know how to get me my money, or at the very least direct me to the correct channels. Their customer centre keeps making me run around in circles, they simply have no clue on how to assist or deal with clients. Some of the staff are extremely rude and arrogant, they talk to you as if they're doing you a favor, unprovoked. Gone are the days of professionalism, very disappointing coming from a financial institution.

So if anyone on here has had a similar problem with this bank please assist on how I can get my money from them.
