I don't know who's calling my home, either. But same with me they never leave a message and have called all hours of the day. For more than 2 weeks now, they have been calling my number. Their number shows up on my caller ID and my caller ID reads: LSAN DA 01, CA #213-537-1370. I agree it's quite annoying. I never pick up my phone if the number or caller's name is not one that I am familiar with. I was almost scammed once before, too (by a different place, asking me for my bank aact number). It's scary to think what they are up to.
just got this call at work was not available. Girl left message named Michelle. Same as the rest c/b busy. She said she worked for Favorite credit card. Still checking. My work phone is unlisted.
