Dont want to release my funds

I have spoken to Tatum who is a call center agent for the Forex department at Standard Bank, and advised her that I have incoming funds from Europe, after doing the security check she asked if I am aware of the funds, I advised her yes and that funds must be deposited back in my account, more then a week passes and still no funds, so I call the call center back and this time I speak to another agent, advising me the note on the system that Tatum added I was not aware of the funds and I requested the funds must be send back to sender, I advised this agent that there was a mistake and I want my money, I checked with the sender of the funds Standard bank never returned the funds, I want my money...... I regret the day when I switched from FNB to these useless piles of ****.... hands down the ***est bank in SA.
