these people leave recorded messages, wanting to sell some kind of health plan. I hate people soliciting me on my cell phone.  How do I block them?

Claims to be for some health care thing. SPAM CALL!!!  It's such a shame they allow calls like this to cell phones.

I got one of those calls too but i did not answer and they left no message. Thanks for the info kvic! Call is from Tacoma WA

30 minutes into a call my call was interrupted by 253-964-3018. My side of the call received the solicitation for a product while the party to whom I had been connected received music. I pressed the one(1) option [the two(2) option was offered to hear more from the solicitor] and I was returned to my original call and the music stopped for my friend. The call proceeded without further interruption.

We use MagicJack Internet service - it seems from other people here that cell service and landlines are equally annoyed by these criminals.

253-964-3018 called and did not respond. When called back said the number was disconnected.
