unsolicited spam recorded message from company soliciting business services they called a cell phone on the no-call list.

Did not answer - they left no message. I am sick of these unsolicited calls, especially when my cell number is on the do not call list.

The government's "Do Not Call" list is worse than useless.  I noticed that whenever I put a number on that list, I immediately started getting many times more spam and scam calls then I got before I put them on the list.  It's obvious that that spammers and scammers use that list as a source of numbers to spam and scam... exactly the thing it is supposed to stop,

Don't put your number on that list or it will get worse.

I wonder how many billions of dollars of taxpayers' money is being wasted on that list and all the useless bureaucrats who run it.

I also did not answer and they did not leave a message.

Same here. No message left.
