Same scam resurfacing

Received a call today from "Medicare." He asked if I'd received my new Medicare card. I played along and said no. (Medicare is NOT sending us new cards). He asked when I signed up for Medicare - look at your card, he said. I told him I must have left my card at the doctor's office last week. He then asked for my husband's card information. No husband information available I said. He will call me next week at which time I'll give him incorrect information and at the appropriate time, I'll tell him to get a real job and stop scamming people and ask if he knows what KARMA means
