E-transfer blocked after money sent

Hi, I sold some gold via e-transfer. Next day I try to sell to someone else, get a message that says my bank acc has been blocked for e-transfer. Call my bank and they say its probably the involvement of fraud and that I have to go to a branch and prove that I was a victim

Anybody have a similar instance?

What would you do?

 

Go to the branch and explain it and see what happens? Why ask us on an online forum when your bank told you how to fix it .

 

I am today, just curious with all thectransactions people have done if theyve had this
