Did you know that you can Report Annoying Callers. If you are getting crank calls, solicitations, or creditors with their annoying sales pitches about fraud security, reducing rates, and all the other programs they try to sign you up and charge you for, you can go to www(dot)reportphonenumbers(dot)com and report the incident. I looked into it, people are reporting hang ups, collection agency numbers and even phone scams where people are trying to collect personal info in an attempt to settle a debt, in most cases the people receiving these calls do not even have associations with the callers supposed company (scary when you think about it.)
You can enter a phone number and see what others have to say about it or post your own complaint. Now there's a good way to vent some frustration!
