I get the same thing from the same number and I'm on the National Do Not Call Registry. what good is the registry when they don't followup on complaints?
I received a call from this number regarding a vacation package I supposedly won when I entered a raffle over a year ago. They said that the vacation package was for a week at a time share and that when I was on my vacation I would have to attend a time share seminar with no obligation to purchase, and that a voucher for a free 1 week cruise (with restrictions) would be given to me upon completion of the time share seminar.
It turns out this free vacation was not free because according to the lady on the phone I would be responsible for paying the taxes and fees (only a few hundred dollars). My tickets wouldbe in the mail as soon as I provided a valid credit card number for the taxes and fees.
Needless to say, I spotted this scam a mile away and did not give her my credit card info.
