Call all times of the day, no one on the other end

I have also been getting calls from this number for the last 4 days straight.  No one says anything when I answer and they never leave a message when I don't.  I am on the "do not call" registry so I shouldn't be getting any of these freaken calls!  Soooo annoying!

I have received 1-2 calls a day for the last few days from this number. A few weeks ago a similar thing happened and when I actually got to talk to someone they tried to give me a "free cruise"...

this # calls 2-3 times a day and never leaves a msg.
