This works for unwanted calls pick up the call but don't say anything.  Put the phone down & wait until they hang up.  They usually do not call back if they do buy ear plugs & a shrill whistle.

This number calls every day and multiple times.  If I do not answer, they leave no message.  Yesterday, they asked for me by first name.  When I said, "this is Maggie", they hung up.  I called the number back to ask the to stop calling me and the number does not work.  They called again today.

Just started receiving calls from this number today.  So far they have called twice.  Caller ID just gave the phone number and HOUSTON, TX.  Both calls rang 7 or 8 times which is a lot for these types of calls.  I just will not pick up.  I turn off the answering machine when I am at home.  My answering machine will turn on after 10 rings.  When I am home, if the caller is persistent, at 5 or 6 rings I will turn on the answering machine for a second and then turn it back off again.  I will do this every 5 rings or so.  They can continue ringing until hell freezes over.

These darn people call morning, noon and night. Once I just picked it up and didn't say anything and turned up the T.V really loud. My husband just answered a call from them and, yelled at them, "Why are always calling HERE." Their reply was Is Mary there.  There was silence and then my husband hung up on them.  

When they call just have fun with them..its a freebie!  Use some ridiculous voice, talk about you cat..drive em nuts-LOL-they hang up sooner or later!
