They called my Work phone but hung up once i answered.

Got a call from this number while I was sleeping ...left no message..I am on the do not call list...

This number (1-469-283-0108) calls my work cell phone about twice weekly. It being an out of area code, I do not answer as I know it will more than likely be a scam artist. I hate being bothered while at work. I've tried everything I can think of, but the telemarketers keep calling and there seems to be an unlimited number of new telephone numbers they come up with.
When I call them, they same they are "Link Media". " A web design firm".

Got a call from this number at 4:15pm, and a guy asked for me by name, then hung up. When I tried to call back to see what this is about, the call fails and will not connect. Very shady. I'd like to know how they got my number.

Called and left no message at 9:45 this morning.
