In order to provide customers with a mechanism to stop the majority of unwanted calls from telemarketing companies, the Federal Government has established a national registry known as the
“Do Not Call” Registry.

Visit the page: http://www.donotcall.gov/  or call 1-888-362-1222 (TTY 1-866-290-4236) from the telephone you want to register in the system. The call and registry are free.
