The lease has the wrong address and apartment on it. The only address on the lease is the landlords... Is this a binding contract?
If someone is stalking you call the police immediately. File a report and ask to obtain a copy for your records.
Once you are safe, look online for a local lawyer that advertises free phone consultations and explain your situation; mention you have a copy of the police report. A lawyer in your state is the only one who can tell you if the contract is binding or not.
