Hi pete,

UI075719025CN was shipped on Jan.11 and there is no further update after Jan 12. This is because the package is sent as China post ordinary package. China Post doesn't provide tracking service for it. It usually takes about two months for it to reach and it's easy to be lost. You'd better contact the sender to give you a solution if you couldn't get it in time.
