We have now received 2 letters from PTP. One stated that our son was nominated by a teacher to participate in a PTP trip. After investigating and emailing PTP I found out that no teacher actually nominated him at all.
Now we get a letter saying our daughter is invited to go to Australia. We don't have a daughter! There was no name of this daughter mentioned in the letter or why they would think we have one.
They obviously send out cold contact letters, get 50% of the genders correct, and hope that some bite and send their "exceptional" kids on expensive trips.
