Thanks for the answer.
In my case I waited for 11 days, rang PP and they said the payment was completed, seller should have the money. I emailed the seller and asked for the tracking no, she replied me the next day that she would email the tracking number shortly.
No emial for the next 2 days ...until I asked her to comfirm if the item is authentic and it has all the nescessary authentic stamps or else refund me the money.
Seller got back to me 2 days later and confirmed item is authentic but since I have doubted the authenticilty she refunded me the money (still pending).
Why she did not ship the item at the reasonable time and did not contact me until I emailed her?
Did I pissed her of asking for the authenticity confirmation?
Now I am a bit regret that she put the item on auction again and I don't know if I made the right call.
