Just received a message from 210-774-4141...it was cut off....all I got was "attorney, please call 210-774-4141"...I've received these calls before.  If you do end up calling (which I recommend you don't) just ask for everything to be sent to you in writing, certified mail. Do not give ANY personal information. Any legit company would already have your info. And DO NOT give them any money.  In my state of MN - you do not go to jail for not paying your bills.  I'm pretty sure that is true in all states. Not paying your bills is not a good thing - makes for a bad credit score. And by all means contact the authorities if anyone threatens you.
