Most of people sick of being called so frequently from telemarketers and they do not know what to do to block such calls. If you have the same situation then you are on right place. Got this from
If you don’t want calls from telemarketers, you can register your phone numbers on the National Do Not Call List at www.donotcall.gov or by calling toll free (888) 382-1222. You can register cell phones too. The do not call list is operated by the Federal Trade Commission (FTC).
Registration is effective within 30 days and is good permanently. Telemarketers should not call you after you have been registered for 31 days. If they do, you can file a complaint with the FTC .
People who you do business with and most charities can still call you.
