Answerd the call from 404-793-6004. Person's question was can you hear me? I answered yes which I hear can be used against one. Then I said I am not interested. Something about a disney tickets.
Received a call 30 minutes ago. Said they were warranty dept. They said "CAN YOU" at that point I hung up. Clark Howard said it is a scam. All they need is a yes and they will use that yes to scam you.
Another iteration of the "Can you hear me?" scam. Number blocked. As James says above, don't say anything if you hear those four words...they can be used to rack up hundreds of dollars in charges without your consent.
