How to stop it? How to fight it?
Until I found the great websites that giving user the opportunity to expose who is on the other end of those annoying phone calls. The websites is CallerWiki.net. They make it easy to find out any number in the U.S. Caller Wiki helps us unmask the people behind these annoying phone calls. You can also Report Callers by going over to this web site.
This websites very useful for me. Also, with Caller Wiki we can post specific information about the caller. If you receive a call and have no idea who it is, get the number registered in your phone and enter it to the search box at Caller Wiki. You will then see the information on that phone number, the result will also reveal if there are Caller Complaints for that certain number. Don't hesitate to visit this sites.
