well, here's the sitch:
   buying on ebay is always a risk, but it's your 
choice to take that risk to get great merchandise 
for cheap prices. hopefully the dealer will be 
sympathetic and take the cel back, but if not, 
there's not much you can do. you can leave 
negative feedback if you wish, but that can 
result in you getting negative feedback from the 
seller. I've been screwed before and have since 
learned that sometimes letting it go is the best 
thing to do, unless of course you paid hundreds 
of dollars for something(which in your case you 
did not).
