they called in the mid afternoon some sort of sweepstakes entry gimic,Everytime I answer they scream HELLO 4 to 5 times then hang up.

they leave message saying i'd won something like an expedition or explore and to hurry to call back......

Sweepstakepromo. Telemarketer Scam to sell travel packages. You have 1of 4 possible prizes! Must attend a "gifting ceremony" to get your scratch card to see what you won. At the gifting ceremoney you will be subjected to a 90 min. high pressure sale for vacation packages and a convoluted points system. Rip-off. Do not be a sucker.
