Don't know this number

Same - got a call from this number.  Don't know it.  They didn't leave a message.  I wonder if it's the same people who called yesterday and didn't leave a #. 312-470-0736.  That turned out to be some sort of scam company.  Look that # up and you'll see.  I'm Pxxd that they have my cell #....

Has to be a scam.

Don't know this number, didn't leave a voicemail or anything.

Left part of a message.  Something about a free trip.  I don't enter those contests.
