can i know what type transportation best express use?

cause i have parcel send out from their shah alam warehouse since Saturday but till now still on the way.
called their customer service, they said my parcel On the way, but when i ask on the way to where or from where (Shah Alam to Penang or) ? they reply, don't know, not sure where my parcel at.
Might be Shah Alam ware house, might Be Bayan Lepas warehouse, Might inside lorry, might be out side warehouse as they have no clue......

for me i think they use bicycle, that why can't trace (out of battery).

local.
taobao use best express ?

saturday from SA warehouse but till now still no update.
