I bought a Rimowa carry-on luggage in Frankfurt airport on 24/6 and the sales lady told me I could get a tax refund after I passed control. I was flying out from Frankfurt to Hong Kong transiting Amsterdam so I was at Terminal 2. I found a government export/customs office in Terminal 2 who's supposed to give me a stamp on my taxfree slip. But the lady officer said I could only get the stamp after I pass control. So I passed control but found that there was no government export/customs office. Is this all a trick???
I posted this query on the premiertaxfree.com but no reply whatsoever. I feel this is all-in-all a cheating stuff.
