Hi I work for the phone co. We get inquirys about these types of call's. They are ALL scam artist trying to get your personnel information. So they can use it, sell it, trade it, hack into your computer. The phone company cant really do anyting about, since these criminals keep switching there phone or ID once they get caught. Thay have such a long crimnal record of ID theft and everything else, that jail is simply a second home. Besides the jails are so over crowded that they know the judge will release them soon w/probation. los angles is #1 in ID theft with new york 2nd chicago 3rd. Watch out for the one to rewarranty your car.
