Landlord refuses to renew my lease based on false information/harrassment from another tenant, is this legal?

State of Missouri, I live in a condo and have been being harassed by my next door neighbor, whom I've never met. She had been falsely accusing me of having wild parties, calling the landlord and telling them that I have all these wild parties. The other day she called the cops on my deaf/hearing impaired buddy of mine, stating that there was a domestic disturbance, when in fact he is just loud when talking! Now my landlord refuses to renew my lease based on all her false accusations! Do I have any rights that could protect me? I have 24 days to find a place to live! Help!
