Non-refundable and non-consumable securitydeposit

Hi, last September 2, 2018, we rented an apartment here at Mandaluyong for 7k per month. The landlady said that we only need a 2 month-security deposit so that we can move right away. My friend and I agreed on it and pay the 14k on cash. However, the contract was just sent this September 11, 2018 and as I was reading the paper, it states that the security deposit is non-refundable and cannot be consumed. My friend and I got worried because 14k is not that easy to earn and it took us a couple of months to save that. I asked the landlady as to why we can't consume or refund the deposit if in any case we didn't damaged the unit and she said that they will use the security deposit once we moved out and restore the property again. My only concern is, is it really non-refundable? Or in any case cannot be consumed?
