Calls from this number has to be some type of scam!!! The '313' area code is for Detroit MI. They called me on 12-16-2014 on my landline. Hung up as soon as I heard a message that Claimed I had won a free trip. They called again on my landline that same day while I was having dinner. I did not answer the send time since I recognized the number. The called me again on 12-17-2014 on my cell phone. Again I did not answer. Don't know how they got me cell phone number since I only give it out on a need-to-know basis.
