Calls constantly on my cell phone and work phone. At least 4 times daily. The number is currently registered through an Ameritech/AT&T landline to the American Purple Heart Service Organization - which is an F rated Charity by Charitywatch.org (formerly AIP). The bot they use just calls constantly and from a couple different numbers.
They keep calling and won't leave a message- shows up on the caller ID as Marshall, Michigan. I've answered twice and both times there was nobody on the other end- Very annoying.
