got the name Danny Shockley on our caller ID but when answered no one said anything !!!WTH????

no message, hangs up as soon as machine picks up

Hangs up as soon as answering machine answers
Caller ID shows unknown name

Something has got to be done about these harrassing annoying calls
To do a search for and find info, don't know why all these companies want to charge money to find out where they come from. It's us that's being pestered
above and beyond. Just so sick of unwanted calls from unknown names
These people have to know how much we hate them.
