do they have the right not to pay my pondo

hi atty.,
Just want to ask your advise;
I was employed to a multinational company last Feb 15 2011 up to 11 July 2011, my story goes like this . . .
i was hired last 15 February 2011 syempre under probationary ako til 6 months, pero i decided to file a resignation last 11 June 2011, in the contract that i signed that i should be stay 30days from the date i filed my resignation, apparently i didn't complete the 30 days i leave the company on 30th of June 2011 and didn't come back to them anymore.
my problem is, i still have a 1 week na pondo to them which they are not giving it to me til now.
My question is do they have the right not to pay my 1 week na pondo to them which i have work for, sayang kasi?
regards,
Bartu

you can claim it, but they can also claim damages against you for not completing the 30 day notice period. your remedy will be to file a claim at nlrc.
