I received three missed calls from this number and when calling back was told I would receive  $100 gift card to Target, Walmart, Best Buy, etc. Afterwards the salesperson assumed I agreed to this and asked for my credit card number to pay $4.95 for shipping(papers should not cost more than $.67 to ship.) I asked to speak to the manager, her name was Nancy, and when I asked why I had to pay for her to sell me a product she hung up on me. My number is on the do not call list. What legal action is available?

Called on my cell phone, only one ring (though I wouldn't have answered even if they'd stayed on the line long enough for my voicemail to kick in). I don't ever answer calls I don't recognize. And if they don't leave a message, that's a sure sign it wasn't a call I needed to get anyway, and I sure won't return the call, since that just lets scammers know that yours is a live number that they can then sell to other scammers.
