"you are a telemarketer, and I don't do business with any company that uses telemarketing as a form of advertising" (stolen from a comment on this web site -- I love it). And do not answer name unavailable ever as calls are now starting to say that often.
Let me explain my idea of robo calls. Each area code has 9,999,999 numbers fyi (7 digits). The program starts calling every number that it can in succession. So they don't need to buy or obtain lists from anyone. I am going to copy and paste and post this info for each number that calls me for this web site.
Nothing is going to stop these scammers and lazy collection agency who call everyone with the same name instead of looking up the right one and all we can do is block them or use call forward selective.. DNC does not work when they are robo dialing all possible random numbers. The authorities can not or will not help either.
So, just block them, don't answer unknown calls, and continue using this great site for information to be in control of your own home and cell phone calls. If it turns out that you did not answer a call from someone you know (number not on this site), just call them back. No problem. Its alot of work that I do (checking the number on this web site, blocking the caller, and making my own excel spreadsheet of numbers) but at least I FEEL like I have a little control of the situation. Maybe I'm delusional.
Its our life and we need to take it back.
