From experience, when You're getting items shipped from countries such as Korea, the tracking information takes FOREVER to update.
If you're package is saying its in Icheon, that will be the last place it stops, before getting sent to you're address, overseas etc. It should and will get updated once it hits you're country, which could take weeks 2-3. Now obviously if it hits a different country asides from you're own, they've obviously sent you're package to the wrong address, and you should contact them to send you a new one out immediately or get a refund.
But yes, Tracking, and shipping wait times are ridiculous!! I really hope there is no problems with my boxes getting here, because Ive had enough problems in the past with shipments from Japan and China.
