Boy do i love playing with these people.

These jerks called and didn't leave a message. I already knew it was a scam due to the pattern of the calls.

Got the call from these toolbags as well.  Decided to screw with the person who answered the phone, he wasn't amused but I did get the chance to fluster him and waste his time.  Everyone should talk to these people just to waste their time and anger them.

They call & don't talk!  What's the point then?  It's just a waste of my time!!!

numerous calls every day and evening.  they never quit
