they call me every once in a while..no voicemail, when i answer they hang up, when i call back the number isnt in service.

i'm assuming it is the cops, there is no other explanation unless someone can give me one..

i will check back soon on this site to see whats up.

There was a reply before mine but somehow got deleted? makes no sense, must be the person calling..

100% cops, aliens or cops.

they call me every day i call back the number isnt in service. i check caller id it says williams,coal & 2016589265

They call me numerous times every day  and hang up. I call  back but it says not   in service.   Really starting to be annoying.
