Ok, it sounds like you used two different methods of shipping, one would of been SAL, which can take anywhere from 10 days, up to 30 days, for the one that arrived within a week, you had to of used either EMS or FedEx, those are the only two that would get their that quickly , and both of those have tracking, whereas , standard SAL does not have tracking.
I have always had great customer service with HLJ.
