Number calls and today left a message on my voice mail that seams to have been left on an accident. Well I found this on Face Book: there is also a picture of The man. It's weird why would he be prank calling me???

Ok it's been almost five years but it's time to say goodbye to my old phone number so bye bye 916 470 9699 no more now you can try 916 740 6207 the new one

I've been getting these call for several years.
This what I've found to be pretty effective.
I made a list of spam callers phone numbers and when one of them call, I answer with
AN INDIAN ACCENT AND SAY HELLO, HELLO, HELLO, AND I DO NOT INGAGE IN CONVERSATION WITH THEM. This drives them crazy and they hang up.
Mission accomplished! Then they put me on their DO NOT CALL LIST. !!!! I win.  

Now, those call have dropped off a lot.
It works for me, Try it You'll like the results.

They have called me before and when I answered there was no response so I hung up. They called a second time a couple days later and when I answered, a woman said "I don't know if you know this but I have been watching you"

Caller leaves no message and when called back. Doesn't answer or doesn't even ring. Please beware. A new scam can collect your information just by answering the call, even if no one is one the other end.
