Victim of ***** & My Account Gets Frozen

A colleague asked for my cell phone number to transfer funds to my account so that I could transfer these funds to a friend of his. The person sending the money (a employee of Capitec) insisted on a Capitec Account. I willingly gave my cell number, received the funds and made an instant payment to my colleague's friend. A month later, my account and funds are frozen. When visiting the branch, I was told that the account from which the money came from has been involved in *****elent activities. How was I meant to know this? I was simply helping a colleague out and as a result I now have issues with my own finances. I have been a good client of Capitec and in an instant, without my consultation - my account and funds are frozen. What's even more ridiculous is that the money (I did my own investigation) came from a Capitec employee! Surely you should investigate this?! I have been told that my account will not be re-opened. It is ridiculous that my name is tarnished with a banking institution due to an employee's actions. I am seeking legal advice on this matter. This is purely defamation of my character and has been a huge embarrassment to me. It has also complicated my life and put me in a financial situation. I understand that your ***** department sits in one room trying to deal with all of your branches queries but too simply freeze and account and not consult with a loyal customer is ridiculous!!!
