Hi If You Are Talking About a partular Number then contact your telephone service provider and explain your problem to customer service and they should be able to block the number(s) for you. or if you are recieving alot of calls from diffirent numbers they might be able to change your number if its that bad. if you dont know the customer service number, tell me the service provider name and i well get the number for you. good luck!

I assume that you are in the United States. If so, and this is a personal rather than a business line, then the majority of calls will be stopped if you register with the 'National Do Not Call Service', regulated by the FTC and the FCC, who class it as an offence for telemarketers to call numbers registered with this list. We have a similar service in the United Kingdom called the Telephone Preference Service, which is very effective at stopping unsolicited phone calls, whilst Canada, Australia and New Zealand bodies operate similar schemes.
