Wake up people, these companies don't care about the Govt. Do Not Call List. I finally bought this call blocker...http://www.digitone.com/
Before I purchased it I made a list of about 20 numbers that had been calling. When I got it in, I added all of those. It's been peace and quiet since I got it about 2 week ago. I have added a few more numbers since. Oh, by the way, it holds 80 numbers that you can block.
If you give these people your credit card they will take you for the ride of your life. DO NOT GIVE THEM ANY INFORMATION. If you already have given them your credit card, call your credit card provider NOW!
Even if a caller sounds so nice, the caller is a wimp that spoofs numbers and hides behind a computer so the caller doesn't deserve a dime. What the nice caller deserves is a jail cell with a dim light bulb. A 20 watt would work. No 3 or 6 meals per day. Just 1 meal is enough. It sounds barbaric? Yes but these pretending nice callers deserve it.
