Called amnd said they were from Medicare/Medicare Advantage. Went in to say they would give money back, etc etc. Initially when I said they should understand if I was suspicious and thought it might be a scan, they said if it was a scam how could they know her name, address, birthdate, etc, which they gave. When they asked if her plan had vision, dental etc I said yes. They then asked if she had prescription plan with no copay. I said she had zero copay at which point they hung up. It was a scam
