Who called from 4177202806

Called.  Nothing but silence and then it sounded as if they pushed a key on the phone.  Nothing more.

They called claiming that Centurylink had new internet service available in our area and wanted to talk about switching our service provider. I told them to check back later then checked with Centurylink.  They confirmed that internet IS NOT availoable in our area. Please be careful with this company. Not sure what they are up to.

Called and left a message saying "BOOM! Century link rules!  You got Bombed!"  Then hung up.  No idea what this means.

no message...dead silence...SCI on the caller ID

Answered their call, they said "hello" then asked "who's this?" and then hung up on me, jerks.
