they removed an item I bought, after i bought it. Isn't it mine at this point ?

[anth-ny]

A half hour after i bought an item, i got this message; We're writing to let you know that we've removed an item you recently won. Since you've already paid for the item, you don't need to do anything else. If your item hasn't arrived yet, it should arrive soon. If it doesn't, then you'll want to open a case in our Resolution Center. Thanks,  eBay - Please don't reply to this message. It was sent from an address that doesn't accept incoming email.-  OK, the problem is, i already bought it, so it is my item now and i want it, NOT the refund from a resolution center. who is responsible for what happened and can i get the item or an exact replacement ??
