Says they are a law firm and i need to pay them 600.00 with a debit card to avoid them filing a lawsuit against me for an unpaid loan which i have no loan other than my auto loan. Accoring to calbar.org they do not exist.

The samething has been happening to me, i returned the call and informed them to fax any information regarding the case to me and i would give it to my att. well they keep hanging up on me, go figure

I have been receiving harassing phone calls from this number as well.. Claiming to be a law firm.  telling me i am going to be arrested for a loan that i didn't pay back.
i know i never took a cash advance loan.
they will not even give me a date of transaction.
