I got an email this morning from Dennis McKeon of WhereToTurn.org that in the next few days that all cell phone numbers will be turned over to telemarketers, and that you will be charged for these calls. So it is imperative that if you want to avoid these unsolicited calls, you must again register on the National Do Not Call list.
It is very easy to do, and takes about a minute. Just call 1-888-382-1222, or go to the web site at www.donotcall.gov. You will be registered on the list for five years.
It's worth it to keep these pests away.
