They are calling from a singles dating site I presume to get more information to help match you with a date. I do not know the name of the website though.

it's a  call from overthirysingles.com asking you to show up with id, check book and credit card to 24255 w 13 mile in bingham farms....sounds like a scam to me?

I have received a call from this number starting Sunday 6/8/14 and two already today.  When I pick up it sounds like a collect call asking if I accept a call from ____________(silence).  I hang up when They ask if I accept.  I don't know anyone in Jail or that would be calling collect.
