weird, couldnt even fax just my score to that number.

You've been scammed.  You just requested your credit score from a company that will charge your credit card $50/month, and they'll sell your SSN and info to someone for identity theft purposes.  Why would they want you to be able to fax anything anywhere?

posts on craigs list n.y a very pricy apt rental for only 1000. a month.
they request submitting yout credit score, and only ur credit score

do u know if their is a contact # for this residental building.

This has got to be only a contact number, I just found this number for a chicago apt listing......
