Called, unknown number

This number calls at all hours. When you call back,  you are either on infinite hold,  or you get the original recorded message of someone  trying to sell you a security system. I've told them to remove me from their list many times. They don't listen.

Answer the call when the Robo person starts speaking continuously press #### then hang up. This should disrupt the Robo call and take you off the list. Try it. Actually it jams there computer call.
