I am being asked to pay a credit card debt that is four years old and I can not pay because I am unemployed.

I suggest you at least contact a local consumer rights attorney to discuss any possible defenses you may have.  Most consumer rights attorney offer free initial consultations.  If you are unable to afford an attorney there are legal aid clinics available in some locations that might be able to assist you.  Please see: http://www.lsmo.org/ This is not intended to be legal advice, and is general in its nature.
