FNB incompetence

On the 4th of October, I sold an individual a ticket and they falsely reported me for ***** in an attempt to refund the money. On the 6th I realized the account was frozen. Since then FNB has been giving me the run around for months. I’ve been calling and initially told me to wait for an email from a detective. I never got it, called again and they told me they sent it to the wrong email. Next time I called I was told to wait two weeks, I waited and the way told me that I need to submit an affidavit, I did and I was told to WAIT AGAIN. I went in to my local FNB and I was told that they weren’t able to do anything due to it being a ***** case. It’s been over 2 months now and there’s still zero feedback or communication from FNB and I’ve really given up. I still have money that’s in the account that I can’t access and I’m really over the situation. Don’t use FNB.
