If you have a telephone company/plan that includes a lot of extra services, e.g. call waiting or three way) you probably have call block too. Look in your phone book or call your phone company and tell them you want this # call blocked and they will no longer get through if they call you from this #. It works! This sounds like a scam to get ss #s or personal info. Very fishy.
They keep calling my house! When I answered they asked for my wife. I said she is not available, and they hung up. Now I am ignoring calls from them and they don't bother to leave a message.
