This vacation spam probably won't tell you anything if you don't pick up the phone.
They say that you have stayed at one of their 'hotels' and are offering a too good to be true discount on a vacation package.
They aren't getting my credit card info that easy. Because that's what you'd have to do to 'book it'.
And I'm not going to do that.
I've gotten the same recorded message from several different numbers these two just this year but there have been more:
215-800-0118 from Philly, PA
215-277-2152 Jenkinstown, PA
The number has been listed inclusively for this website called Legacy for Children's Care - so I'm guessing the number was spoofed. The Legacy site's hosting service is located in France, but (so one site says) is probably from Russia. And on ScamAdviser (dot) com is listed as probably unsafe.
So I'd say 'they' are just 'phishing' which to me is a prank.
