Thank you for the clarification. You now need to send the the landlord a copy of the lease agreement (that shows no one year committment), along with the communications and a demand letter (certified/return recepit) respectfully requesting the deposit be returned to you within 30 days of receipt or you will be left with no other option except to file suit for the deposit owed.
If not returned to you within 30 days, file suit in small claims court for the deposit.
