Hi there,
I just got back from Paris. Went to the store to ask about my refund. I had to talk to the cash register person. SA didn't know anything. He looked at my green form (pink was mailed after get custom stamped). He said how come I didn't have custom stamp. I told him custom only stamped the pink form but not the green one. However, there is a date that the custom wrote on pink form that went through the green form. He told me he will forward this to the team that process this and someone will email me...
Yesterday I got an email. The person wrote that Hermes can't process the refund since custom didn't stamp my green form!!

I wrote back to her to see if I can show other proofs of traveling/leaving the country.... I haven't heard back...
Also, Paris has new VAT form. It's not pink and green anymore. There are two separate white sheet of paper, one to mail and one to keep. Don't forget to make sure to ask custom to stamp both forms. So you can prove to Hermes if you haven't received the refund...
Urghhhhhh, I'm sooooooo sad!!!
