These mega rental corporations just exist to nickel and dime the shit out of everyone and will throw their weight around. You'll just spend more on legal fees, and they bank on that.
Companies that want to play that kind of game don't want to play it with me. Particularly in my state (MA), the law is vastly in my favor, and I am willing and able to spend the time proving that point. I know a lot of people can't, so i'm happy enough to exact some measure of karmic equivalence.
I learned all about this in the last apartment I rented before buying a house. I was trying to work with the property management companies lawyer over how much it would cost to replace broken door (another long story), and the lawyer was of the mind that I owed them more than I had on deposit and I should set up a payment plan ASAP.
The 14 day limit passed and I got a summons that I was being sued for $1500 over the deposit for a couple of small things plus a empty heating oil tank (heat wasn't included). They said it was full when I moved in, but I produced a receipt that I paid for the tank to be filled on the day I moved in along with a voice mail from the actual landlord that said I didn't need to fill the tank when I moved out.
The lawyer immediately wanted to "settle" with them keeping the whole deposit, but I was happy to go to court. We were in front of the judge for less than a minute and they ended up paying almost 1/2 of the first year of my mortgage.

> What if the landlord doesn't provide a full refund, or a statement of deductions and a refund of amounts not deducted, by the end of the 21-day period as required by law? According to a California Supreme Court decision, the landlord loses the right to keep any of the security deposit and must return the entire deposit to you.
The best thing you can do before moving any of your stuff in is document any defects in detail (every single apartment has them).
The best thing you can do before finalizing moving out is to take photographs of how you left the place for evidence.
Ideally you have before/after photos to demonstrate things that may have been defective before you moved it but that you may be (mistakenly) charged for. Most people don't do this and have little recourse when the bill shows up.
