1. Pressing 2 won't help, especially if they're not legit, which they probably are not.
2. Do NOT call any of these numbers back as you can incur very high long distance charges. This is a scam that is going on currently and something to be aware of.
3. Never answer these calls if you don't know the caller. What you've done now is let whomever know that yours is an active number and guess what? You will receive more calls.

Be aware that these scammers can "spoof" numbers, that is make any number appear on your caller ID like one from your local area code(s). Invest in a Tele-Zapper or T-Lock incoming call blocker (search Amazon for these). Until and unless Congress or the telephone companies can do more to protect us, it's up to us to stay proactive. Please just don't answer these and don't call them back.
