This call is a robotic call claiming to be a contest. The way this scam work is that they will call randoms numbers and sew which one gets action (picked up or voice mail) once they know this is a live number they then sell it to scammers overseas so that they can try to do various scams on you. One of the ones they tried on me was calling and hanging up, if you return the call you are route and re-routed to a 1900 number. The number asks you to press 1 to be removed. you will then hear, "your number has been removed, thank you........ a $49.99 service fee will apply" most people hang up after the thank you and never hear that after the long pause you are being told that there is a huge fee for removing the number. this is a SCAM.
For everyone dissing the DNC list: it does work. It prevents LEGITIMATE telemarketers from calling you.
If your number is registered on the DNC list, you can be assured that these repeated or annoying calls are coming from crooks, not legitimate telemarketers. Most often the calls originate from overseas call centers, despite what shows on your caller ID, which these days has been rendered nearly useless.
The DNC has no jurisdiction in the countries where the calls are coming from.
