This is another scam.  A woman asked for my husband, but said our last name wrong, so he said that that person wasn't here and could he have him call her.  She told him to tell this person that he is needed at the doctor's office ASAP!!  They don't block they phone number because they want u to call that number, which hooks u up to a person wanting important info about u....like bank account number, etc!!  DON'T call them back!  They are out of Los Angeles, CA and had a Spanish accent!  I had previously heard about scams like this on our local news station several months ago, but I guess they are still at it!!
