TO ASK FOR A REFUND?

MY PARCELL HAS BEEN SHIPPED ON THE 7TH APRIL BUT SINCE 28TH IT'S STUCK IN PVG AIRPORT. IT'S TWO WEEKS IN THE AIRPORT AND I WANT ALREADY TO ASK FOR REFUND BECAUSE I FEEL IT GOT LOST OR STOLEN THERE. I HAVE ORDERED ANOTHER ITEM FROM CHINA 2 DAYS AFTER AND YET THE MESSAGE ON 17TRACK IS '2014-05-12 17:42, Information Received (This is not an acknowledgment of the physical receipt of the stated Registered Article)'.
I HAVE ALSO ORDERED FROM DIFFERENT COMPANY IN CHINA ON THE SAME DAY AS THE FIRST ITEM AND THEY SAID FOR ECONOMY SHIPPING THERE IS NO TRACKING NUMBER BUT THEY OFFERED ME A REFUND IF I DON'T GET IT BY THE 14TH OF MAY.
MY QUESTION IF I SHOULD ASK A REFUND ALSO FOR THE FIRST ONE NOW OR THERE ARE CHANCES AFTER 50 DAYS THAT IT WILL ARRIVE (NOW IS 50 DAYS).
