venmo Scam Unprofessional Poor Business Practice Internet

I sold some tickets and received payment via Venmo.  Soon after I received payment, I initiated a transfer of the money to my bank account and Venmo advised that the transfer would take several days and provided me with the estimated date.  I checked my bank account and the money never arrived so I contacted my bank and they told me they never received anything from Venmo.  I then contacted Venmo and they told me that they froze my account and returned the money to the person who I sold the tickets to because I was in violation and to go back to the person that paid me the money to get the money back some other way.  

The game had already been played by that time and the person would not return my emails or calls.  Venmo should have just held the money until the issue was resolved instead of giving the money back without any warning.  They never contacted me about my account frozen account and if they did, I would have just cancelled the tickets sent to the buyer.  

Right now I am down a lot of money and I'm not sure where to go with this.
