There are things you must consider in this case.

First of all, You have signed the contract and the agreement prior to moving in the apartment. You are as well must pay the rent based on what is written on the contract.

However, there are things you can do for you not to pay for the rent. The best advise I can give you if you have damages in your apartment that you did not cause:

1. Talk to your landlord (usually they have a rental office in the apartment complex itself) and tell them what is wrong and what needs to be fixed.

2. Next, write a letter to them explaining what is wrong and what needs to be fixed. Keep a copy for yourself.
Finally, call your local housing office. Most city or local governments have people who inspect houses for problems. Ask the inspector to visit and show him/her all the problems.

3. If your landlord does not fix the problems, you may be able to make a legal charge against them.

It will be analyzed to determine the best course of action. In most cases, a letter is sent to the business involved requesting that it respond with their position about the complaint. The unit investigates every complaint and will follow through by notifying you of the results.

If you have made up your mind and you want to file a complaint you may visit this page: http://www.rentalprotectionagency.com/complaint_center.php for you to officially report your complaint.

I wish my comments could help you resolve the issues you are facing right now. Best of luck, Susan.
