Didn't answer only one possibly political

Called today and left a message about making my healthcare policy better.

United Healthcare regarding services offered.

This number has called my house at least twice a day, I never answer the phone when they do call, but here is the annoying part= I'm on the NATIONAL DO NOT CALL LIST! As soon as I put my home and cell number in it a few days later I start getting phone calls from these people. Why should I answer their calls? For all I know they could charge me a fee for how long I am on the phone talking to them. Also they must not be important, they don't leave a message so forget it.

Got a phone call from this number, when I answered, an automated recording said, "Please hold for important health information," and then I heard recorded music, punctuated by "We're sorry for the delay, please hold." I waited for the message to cycle four times and finally hung up.
