It's called 'caller id spoofing'. The people calling you can make any phone number show up on your caller id. They're making a number show up that charges you money if you call it and press a certain key.
At the same time they've disguised the messages on their pay by phone system as surveys. Those messages normally tell you what you're buying and how much it costs.
Check your bill for unwanted charges if you called this number back.
This is not a political survey, no political survey can give away 2 day cruses as this claims it will. This is a timeshare scam with the call originating from India via voice over internet protocol and a false US POTS caller ID message. It's fraud at the worst level and exactly why I opposed PIPA and SOPA. If this can't be stopped over phone service with laws that should prevent it - the the government can't "manage the internet either. Give -me- and affected citizen the authority to prosecute this and I will, but don't trust a corporate owned government bureaucrat that power - they'll abuse it and this kind of problem will increase exponentially. BTW at 3pm this day the automated scammers running this are gathering data on the 770 area code in Georgia.
