Yes, I would try to contact the sellers! You 
should not let this wait too long, since Ebay 
will not protect you after a certain amount of 
time.

Hopefully, you had the cels *insured*. If you 
did, you can ask the seller for proof that they 
sent it and ask them how long ago it was sent. 
(So you know if the cels might be lost.)

If the seller will not contact you any longer, 
here is the URL to go to so you can get more 
detailed personal information on a seller on Ebay:

You want to fill in the "Contact Info" section of 
the form and they will send you the address and 
phone numbers, etc, that the seller has on file 
with Ebay.

If it's been a resonable amount of time, and you 
can't contact the seller, or the information in 
the seller's file with Ebay is false (like a 
disconnected number), then you should file with 
Ebay for fraud. Here is the link:

guide.html

But mind you, the most you will get from Ebay for 
any one fraudulent transaction will be $225. So 
you wouldn't be eligable to get more than a total 
of $392 - assuming that the prices you list above 
are your actual winning bids on the cels.

Good luck! And like I said - try calling the 
seller first. Sometimes just getting a call from 
a bidder is enough to scare them into action. 
Also remember, he has no idea what your voice 
sounds like. So if you feel uncomfortable 
speaking English, maybe enlist the help of a 
friend who speaks it natively or with more 
confidence - get *them* to call the seller while 
you're sitting there and have them simply pretend 
to be you. ^_~
