According to the email, CDs and DVDs " are not a quarantine concern", so they gave me a list of questions. But I don't think they are going to like the answers:
a) The stamp number on the back of the yellow pamphlet,
There isn't one. It was just folded in half and stuffed into the bubble wrap envelope that the DVD was mailed in. I have it here and could scan or photograph it for you.
b) The 3 letter code that is on the yellow tape on the exterior
of your parcel,
Again, there isn't one.
c) If there was any other markings on the parcel other than
Postal information,
No, the only thing on the parcel was a shipping label with contents
listed as DVD.
d) Was your parcel appropriately sealed on delivery,
The bubblewrap envelope was taped shut, yes, but the dvd was not properly inserted in the DVD case.
e) what else was in the parcel with the dvd product?
Just the dvd and sales receipt.
Seeing as there is no Stamp on the pamphlet or number on the tape, it seems to me that someone wasn't doing their job correctly, and without those bits of information, there's no way of knowing who mishandled the DVD.
