well, if it is really lost in mail, then nth much you can do also.
cos you cant track n everyone can just push the blame to one another.
even if the seller never post out, you also wont know.
tts why always best to use reg mail, the seller cant deny n your mail wont get lost.
n if it gets lost, still can get money back.
so i think take it as a lesson learnt, n use reg mail. after all, only $2.25 more, better than items lost.
