Whereabouts of my package....

  So I ordered from Clobba before the deadline, I asked it to be shipped via Registered Airmail, and the dress was finished before the start of Chinese New Year. I was sent an e-mail with the tracking number and proof photo Monday, stating my package had been sent to the sorting facility. It's been six days, I've checked everyday since Monday, and I have no idea where in the world my package is. So, now what do I do? Panic and try to contact someone, or calm my tits and wait it out.
