I keep getting calls from 515-460-2739...they let a message about lowering my interest on credit card...I tried to call back but the number doesn't work and funny thing is I have  a 0% interest card for a year that lasts for a year and a half...so this must be a scammer

Left no message.  Called my cell phone and I'm on the "Do Not Call" list or so I thought.

This company calls to get CC info. I returned the call to get the name of the company but it is a non working number.

a call came from same people a month ago but it said from Louisiana not Iowa on that one, when I began to question the guy, who had a foreign accent, he got indignant and stated, "what you think I am a scammer, I said yes, he got very angry and hung up.  From the sound of his voice it seems to be from Nigeria, I have traveled to several African nations and each has a different sound.

Many posters in 800notes claim the Do Not Call List (DNCL) is not working for them.  We constantly attempt to find a way to explain what the DNCL really does, at a level these posters can understand.

 Perhaps this table will help.

Type of callWill DNCL
Stop?CharityNO! PoliticalNO! Preexisting Business
(within last 18 months)NO! Legitimate Telemarketer YES  SpammerNO! ScammerNO!
Remember,
The DNCL is NOT a call blocker!

Why doesn't the DNCL stop the other calls?
Charities, political calls, and non-sales calls are exempt. "Business relationships" may be exempt. Criminals do not obey the laws, and happily ignore the DNCL.
Want to stop unwanted calls without depending on somebody else to do it for you?
Obtain a call blocker.  Google is your friend.
