I had purchased from dior Galleries Lafeyette (Paris) and had completed the tax refund from self help kiosk there. We left Europe from London and we had our tax form stamped at the airport. The tax form wasn’t returned to us and being taken back by the custom officer there saying they will sent the form for us.
Would like to check if that is the correct procedure because I had asked the form back for mailing but officer answered that is not necessary. Thanks.
