Person called wanting me to give them my social address and dob so they could give me info on a personal business matter.

I get a call from this number several times per week. I never answer and they never leave a message. I just did a google search and found a lawyer's website that claims the number belongs to "United Recovery Systems" , a dept collector.

The interesting part is that I am not delinquent on any bills or services for a dept company to be calling my number.
