When I answer the phone there is a variety of clicks and hums lasting a minute or less. A male voice, non-amarican accent, says Hello. How are you today? He gives me his name, similar voice but new name every time. Today it was Mr. James Marshall. He has a check for my husband (huge amount varies) its from American Sweepstakes Cash Award. Today he included a 2018 Mercedes Benz. He said my husband participated in a sweepstakes and his name was drawn from (huge number) Today I asked for verification, he offered email or fax proof of his identity. He had my address, I said mail me his proof. He got agitated I hung up. How can I get these calls to stop?
