I got scam by real estate agent.

I'm renting an apartment in a 4 star hotel through an agency. I made a yearly contract with the agency. However after 2 months I got noticed from the hotel that my payment are not go through, I find out that the hotel allowed the agency pay them monthly despite i paid 12 months already, and now the agent i worked with ran away and refuse to pay the rest.

Is it legal if the hotel force me to check out or make me pay the remaining in order to stay? From my perspective, this is the hotel's fault since they let the agency pay monthy.

Does anyone faced the same issue? What should I do next?
