I have gotten 4 phone calls in one day so far today the first 718-530-9134 2nd 718-228-1762 the 3rd 718-228-1762 and the 4th 718-228-1154.  everytime there was a sigh and the slammed the phone to hang up on my voicemail.  They did not leave any other information.  I have tried looking up all the numbers and a couple of them led me back to a travel agency scam.  I figure it is better to report it than to have someone get taken for a ride.
