They called my cell phone and a female said she was "on a recorded line" and asked for someone with an Indian (dot, not feather) sounding name. I don't know anyone of that persuasion.
After reading other posts I see it's a debt collection company as I suspected.
I've had this number for over 15 years, so if they're looking for the person who had the number for me then they're obviously going after ancient debts which the guilty party isn't even obligated to pay! Typical action from a bottom-of-the-barrel company.
