Welcome Fierce, read this:
ebay's fake/ not rightly described items page
Where is stated:
"Since you have NOT been provided with what you have paid for, it does not falls into seller's return policy."
In other words, get your money refunded, and you do not have to send the player back, only out of politeness maybe, and only send the player back if the seller payed you back in full, plus the postage for sendback too.
ps your english is fine by the way, wish my portugese was like that
