This number has been calling me multiple times a week for months. I never pick it up and they never leave a message. Wouldn't it be fun if someone invented a simple device that could be attached to any phone and when a telemarketer calls, a button could be pushed that would emit a loud, screeching siren in the ear of the caller? May not be as effective as call blocking but it would provide entertainment for those who are continually annoyed by these people.
Youtube user recorded a call from this number. Should make it quite obvious that these people are not to be trusted.
