Got a phone call from this number just now, noon on a Thursday. I never answer numbers I don't know, but I got a prerecorded voicemail saying "Thank you for using Waker Upper. Goodbye!" I don't know what Waker Upper is, but my cell phone is registered with the Do Not Call list and this one still got through.
This is basically similar to a wake-up service when you're at a hotel. Someone goes to the website, puts a number in, and says to call at a certain time.
There is an "Opt-Out" option at the bottom of their website that will allow you to add your number to it. They called me at 3:45am last night, because someone came to the site, and randomly put my number in.
People that keep complaining saying they keep calling, how about doing something about it? Go to the opt-out page and it will stop..
As for the national do-not-call list that Aly talked about - that wont save you here, because taker upper thinks YOU added your phone number to the service.
Opt out from the link at the bottom of their homepage, and you're good to go - it'll lock your number out of their calling system
