These calls come from Vacations by Newport www.vacationsbynewport.com They claim I've won $2,500 in Air Miles credit which would help pay for a great vacation in Florida. However, check their Terms & Conditions

You must visit Orlando & Miami and, in each location, attend a 90 minute presentation on why you should buy a time-share. Of course I have to pay the air fare.
BTW, the return number is spoofed... why would an honest company do that?

The time is 1550 mtn time and have just received a call from 613-476-2252. It's a good thing I have call blocking, Now I do not have to worry about it any more
