Some loser ripped my off on ebay?

I ordered two dual core asus eee 1201 laptops. He didn't know the exact specs but he knew that the CPU was dual core. So i looked it up and the only eee with dual core is the 1201n. SO basically I payed for two 1201n laptops. but i got two 1201HAB laptops. The HAB is HORRIBLE! It is a single core CPU, Intel GMA 500 and a 160GB HDD. WHAT DO I DO?
