keeps calling from an anonymous private number.  I don't answer any of these types of calls

Some lady named Emily Mora claiming to be from Law Office of R. Ronald called from this number. When I called back they say it is a litigation office but do not state the name of the attorney. Asked personal questions regarding address and social security number.  Think this is bogus!

Someone from this number called looking for my sister. I didn't feel good about this because my sister has her own number. Not sure what kind of scam this is so I'm reporting it

Received a call from this lady stating she was looking for Steve , that he had put me down as a emergency contact, she stated he needed to have his representative or lawyer to contact them at 626-470-7531, Referencing case number ********
Steve contacted them and a gentleman answered and demanded he pay $1000.00 imediately and threatened him with court.

My mother has been receiving calls from them for a few weeks now and now my sister and I are as well (calling for my mother).  No one ever answers the phone and the number to call ( 626-470-7531 ) does not come back with any true business, only scam reports.  Unknown caller and left an unprofessional voicemail.
