Yup, I had the same problem as well.  I bought a mamiya 7 ($1200) but
returned it within the 14 day no hassle return policy.  It sux because
I had returned the camera back to them within the first week that I
had recieved it.

I first called and talked with Gail (the clerk who I originally placed
the order with), after about 7 days, and was told that the return was
being processed.  So, I waited. After 7 more days I called back and
she said she was actually processing my order at that very moment and
apologized for not having had it processed sooner.  Needless to say I
didn't really belive it :)  Of course, after 3 more days I noticed my
account had still not been debited.  I called back and this time asked
for the manager Scott Faust and explained my situation and he promptly
transferred me to the accountant (I believe her name is Jenny).
Finally, after this last conversation, my money was credited back
within two days.  Anyway, the matter finally was resolved but at the
expense of alot of stress worrying about it on my side, especially at
the amount of money at stake. Thought my wife was going to kill me :)

So, I would advise you to call and ask for Scott, tell him that you
need to followup on your return and that it was under the 14 day no
hassle policy.  He should transfer you to the accounting department
and they can see if your return has been processed or what the status
of your return is.

I hear all the time that KEH is highly recommended but I'm hesitant on
ordering from them again.  Although Midwest Photo. Exchange maybe
slightly higher, I have had numerous orders filled out by them without
problems and have even returned a Pentax 67 ($1000) that was refunded
within a week.  Perhaps that's KEH's way of getting back at people for
returning items back within the 14 day policy :) I wouldn't want to
see how KEH would honor their 60 day warranty.

let us know how it works out,

regards,
