Accepted Fannie Mae Counter Offer... Then multiple bids

[Herlando Y.]

I will greatly appreciate if someone can shed some light on this.

I submitted an offer to the Fannie Mae Home path over asking price with all the proper paperwork. They counter asking for additional paperwork which I already provided. I provided the paper work to the Fannie Mae and the website stated they accepted the counteroffer. I did not hear back for 2 days and they I have to call to find out there was now multiple offers on the house. The offers came from the listing agent. 

Is there fraud going on? Was I already in contract once I accepted the counter and the website stated it was accepted? This is in New Jersey.

Thanks for your help.
