Did I just open a can of worm?

[John Lee]

I submitted an offer with a listing agent for a bank reo property. I did not hear back from the agent or the bank. the property went under contract. I guess their offer failed through, the property is back on the market. I decided to get my own agent and submit a different offer, the agent said my offer cannot be submitted because there is already an offer with other agent. Did I just pissed off both agent? What is my option if i still want the property?
