Hi there,
I too recently had something lost that Celga bid 
on for me through a friend's bid.  But, it wasnt 
Celga's fault.  Apparently the shop that had the 
cel lost it (much to my dissappointment).  It's 
really really imperative that you keep your 
language really simple when dealing with Japanese 
dealers etc.  I had something like this happen 
with another dealer.  He mistook something I said 
(here on the forum actually) as an insult.  It 
was SOooo not meant that way though.  It took 
about 4 emails back and forth to clear it up, and 
some help from other forum goers.  I even 
insulted him by trying to say 'Im sorry" in 
Japanese and not doing it in the right form!  
And, by not using the right form, that is also 
construed as an insult.  Wow.  In the end its 
totally fine, the dealer is still very good and 
I've never had another problem.  Its important to 
be pretty humble with them though, because they 
are providing a service, and with a laguage 
difference as big as English to Japanese, it can 
be easy to mistake things.  Just some friendly 
advice from someone who knows firsthand the 
effects of saying the wrong thing accidentally 
^^;;;
