Unknown caller. when you answer the caller hangs up. Call back you get "you were in a servery, but the time has expired, press 1 to remove your self from the list"
This happen to me about 3 weeks ago. I press 1 and still getting calls.
I received their call around 10:30am this morning, it's a political survey followed by an offer for a free cruise for 2-4 people. All you pay are taxes of $60/person. If you accept that they try to sell you on a bunch of "extended vacation packages" where they extend the vacation, include meals, transportation, etc, all at pretty high rates, IMHO. I played guinea pig and accepted the cruise offer but none of the others (and, boy, did they try to sell me on the upgrades!) so we'll see how it pans out.. Worse case scenario I lose $240, best case scenario I get a cruise for 4 people for $240, middle of the road scenario I do a charge-back on my credit card. So we'll see! Good luck and hope this info helps!
