I received order in UK date was December 24,2015, and I receive mail from DHL to pay custom taxes, and after this - to receive my goods - order W1512050300173355.
I make payment - in January 4th 2016(was impossible to pay early, because of New Year) and two days later DHL RETURN phones back to Singapore!
