the deal with the realtor expired a long time ago.
You could have a problem here if the realator continued to act on your behalf even though the contract was expired. With actions, both parties were continuing the contract. That said, I do think the agent was way out of line to try and renegotiate a new lease or lease extension without and agreement from you for them to represent your interests.
I'm not a lawyer, just took REG so that's my two cents. I think you should be in good shape and the agent was out of line.
ETA also note I believe agency agreements can continue on without a written document for only one year, so if the "long ago" is more than one year, that could make you technically right too.
