Worst Bank ever

The worst bank in South Africa it's been almost 7 days back and worth emails and phone calls with FNB forex ,I received a payment from Russia.... at first they didn't believe my 'Reason for payment ' I send them all documents and proof I have .I email them probably like 10 or more times a day ,still no reply ,they replayed me yesterday stating they can't open the document ,still to this day no reply ,instructions or information as to what's going on where my money is .....fnb states they can't see any pending amount .So what should I do or think ???? ITS DISGUSTING ..I can't wait to close my account with FNB I will definitely not recommend this bank to anyone in SA .My dad and a few of my friends had the exact same experience ..I am extremely stressed out as I don't know who to call where to go for help or anything.As no one seems to be able to assist me what terrible service... I have been dealing with the exchange department- *** I WOULD NEVER IN MY LIFE RECCOMEND THEM TO ANYONE

They reply me now and then at around late midday with 1 email , stating nothing beneficial at all.I have probably received 2 emails at most from them .Yet My money is withheld for what ever reason I don't know..
