I must say that some sellers are really lucky who get buyers like you.....you must be crazy to do such foolishness...
I really doubt if ebay will help you out in any way. Please contact ebay customer care immediately and open an item not as described case and in details say "item not received" and also open ebay guarantee claim and there also mention "item not received".
Give the sellers name here so that all can be careful of such sellers.
