I believe that you have to say to the caller, whether they respond or not, "please add me to your do not call list." As long as you have registered your phone number, they cannot legally contact that number. Please remember, if you have signed up for something online and entered your phone number, you are granting that company rights to contact you. That is why you must ask them to put you on the list. Happy Holiday's!

I haven't answered the call, but they have called no less than 8 times in 3 hours.

Really disgusted with these cell phone calls when I'm on the "do not call" list.  When will these people quite calling!?!  Have no interest in whatever they are selling!

Unsolicited call. Also a call from 515-635-3022 VMS Ames Iowa.

Make a complaint with the FCC. I've had to do that with several of these spammers.
