Who called from 9725217783

I got a call from this number about 20 min ago and it left no voice message. Tried to call it back and says it is not a working number. Then how did it call me?  Scams or collections?  I don't think I have unpaid bills

Just called and asked for me by name, I asked who's calling please. Man said, is that you(my name), and he said thank you and hung up.

I tried calling the number back and voice recording says it is not a working number.

They just called. The are collecting info to clean up databases that they turn around and sell. Data miners. They should add data miner to the Call Types.

Some one called me and there was no answer, I called that number and they didn't say nothing
