Some telemarketer. I'm guessing Go Green Campaign, or whatever it's called now. It's the same start to each call, "Hello, this is [name]. How are you today?"
Same as above. "Mary" started spouting off about energy rebates. I asked what company she was with and she replied "what does that matter?". I replied to her, "because I'm on the national DNC registry and I'm going to report your company". Her response, "Well that's all you had to say" and hung up.
These scammers call my cell constantly using different numbers. I have filed a complaint with the FCC. For others that want to file one, the on-line complain form is at: http://www.fcc.gov/complaints. I also block their numbers when they call with a new one.
