Telemarketer, for lack of a better term. Same experience, no message. I once applied for a call center job. Each person is given a sheet of numbers to go through. So anyones number is just some sort of generated thing. I'm on the "Do not call" list. But, it still happened. And I once had a person say "What to you think that's For, to do that!" But, random calls ceased. From time to time, when it DID happen, I said "I'm on the Do not call list". And they hang up in my ear.
