hi, recently i just finish 1 year contract rent in a condo, then i need to claim back my deposit, i have all the key ,card and agreement and form.

The owner is very smart, in the agreement / One of the tenancy criteria is stated that :
You need to stay here within 1/1/2015 to 1/1/2016, less than that deposit will be forfeited, no negotiable.
so the owner use this reason to refuse the deposit to me. She claimed that I never fully stay 12 months and half way move out, which is an excuse, but i really stay there for 12 month, and pay rent every month, however most of the rental receipt i throw away and do not keep well, mean no proof of rental receipt, but have other proof.(deposit, contract and agreement, and key still with me )

Add: the owner also change the lock of the front door. and my card key become unaccessible .

so what should i do? complain to police and management ??

Updated: yes i had moved to new place to stay, right now is the 13th month and the time to claimed back deposit.

The main problem is :
He claimed that i never rent fully 12 months,
1 of the criteria is You need to stay here within 1/1/2015 to 1/1/2016, less than that deposit will be forfeited, no negotiable., the owner use this reason as an excuse,
because the owner knew i moved out early last few days on December, thus left few days empty for the room.
but i did pay monthly rent however without much rental receipt, basically lost all rental receipt, only left all agreement and key, and deposit proof.
Question: if i take police action, should be no problem right ? mean can take back my deposit right? thats is
