It's some BS Law Firm in California. Don't pick up or respond.

I received a phone call from a blocked number, then the lady said I needed to call 657-200-5701 because I needed legal documents mailed to me. She also provided a bogus case number. This is a scam either A) they want your address or B) the will try and get you credit card number to mail you the fake legal documents. Don't be a sucker!

I had same call from some lady at 714-494-1107. She told me to call a lady at 657-200-5701 saying they needed to serve documents,too.  When I call the 714 number it always goes to a voicemail box so I hang up.
