It has been about 5 weeks or so that I came back from London. As I went to Paris and shop in Galaries Lafayette, I did a tax refund at London airport. As currently now is using the machine to process and to receive the documents, do I still have to mail the receipt to global blue? My receipt have to no stamp,,, Like my Printemps and Selfridges receipt both have stamp… I also remember that I have a customer copy of the tax refund form from Galaries Lafayette but I am unable to track it at Global Blues… Does this mean that I have to mail the receipt to global blue now or so? Will they give any copy of the tax refund form(Customer copy)?
