This is yet another of the many numbers used to try to force you to buy "extended warranty" insurance. As soon as I block one number, these fraud artists will call me from a new seemingly local phone number. I am on the do not call list, so they are breaking the law. They apparently call everyone in my area. And I am sick to death of their robo calls. I have reported other numbers they use. But this has been going on for years.

A lawsuit against me for supposedly taking a cash advance $500 and not paying it back. The scary thing is that they have my last 4 of SSN, Driver's license #, an old address, and a very old yahoo email address I used to have. I checked with my State who says there is nothing pending against me so this is a scam. Not only that but you would get something in the mail, I did not.
