First, you don't have to panic about your cell phone number being released to telemarketers. It is false. If you get those false email warnings, reply to the sender that it is false. (https://www.snopes.com/politics/business/cell411.asp)
You also don't have to panic about the national Do Not Call List expiring every year. It will NOT expire. If you called the number and put your number on the Do Not Call list, it will remain there. (https://www.snopes.com/politics/business/cell411.asp)

I have received each of these since Christmas. I checked them out immediately and sent reply emails with this information. You should always reply to the sender who repeats false rumor trash. If they don't stop it, delete them from your address book and block their mail as "Junk."
