After an hour, I got ready and decided to checkout from the hotel. This has proven the McGuiver in me and was able to transform my many bags and consolidate it into 3 checked in luggage and 1 carry-on. From 6 bags. Wondering why I have so many luggages? I am too. I dont know what I bought really. Maybe lots of souvenirs, basic shopping and my many bulky winter clothes.
Arriving at custom office, it is still closed. So I tried 2 things. One is ring the bell. No response. Then I rang their call centre and the lady on the line probably woke up the officer. He is a bit old and was super slow in processing my refund. Took him 20 minutes as he scrutinizes my documents. Then, finally when all is done. I got the stamps. I proceeded to the ICE refund company who offer services to get the refund back to my card. For some reasons, she said I don't need to give back the documents back to the merchant. Im dumbfounded and still skeptic that if I dont follow the rules, I might not get the refund. So will try luck in looking for a mailbox from Frankfurt my last stopover as I leave EU zone.
Ps, i realised you always have to look back and triple check before you leave. I left my beloved LV scarf at Hilton Krakow airport. Hope they find it and I can get them to mail it to me back in Oz.
