<prompt> Human: So my roommate and I signed a new 12 month lease extension a couple days ago and handed it in to the front office. The extension stated 12 months with no rent increase. We both just received an email stating that they had made a mistake and we could only do a 15 month, or 17 month lease renewal. Not only is it a longer commitment, but it would take us off the favorable rent season which is fallwinter when rent prices tend to go down. Do they have to honor the contract extension we signed? It would seem wrong if they could go against the recent rental agreement since it would be in their favor.x200B;Thanks!  <response>: Did they sign it, and do you have a copy?
