<prompt> Human: Usually my super gives each apartment in the building an envelop to send our rent check in. This stopped in August 2016. Ive sent the checks for August, September, and October but none of them have been cashed yet. I didnt want to send November and December until the three I sent were cashed first. Ive left messages to my landlord and the real estate agency that I got the apartment through no responses. I plan on talking to my neighbors very soon to see if theyve experienced the same thing. I have the money in my checking account that would cover all three checks I sent.To add another wrinkle, I havent had an official lease sent to me since April 2014. Any advice or feedback on my situation would be greatly appreciated.  <response>: You should do some investigating. Definitely keep sending the check. If you cant get in touch with the people who you would normally deal with. Check out the utilities. If any are paid by the landlord make sure they are being taken care of, or if they have been taken over by someone else. If you are responsible for all utilities check with the city to be sure your building isnt in foreclosure or up for sale without your knowledge.
