Dear, Ebay.

 I ordered Dyson V6 on eBay, Seller is dysonoulet.

however, I was dumbfounded by the goods you sent me.
Because, the item was shipped without one(Soft roller) of the main parts.

How do you sell goods without checking the component's components?

I've asked several questions to solve this problem, but Your answer always sends the same context.......

I Don't understand Your Answer "NO".......It was entirely your fault, should I suffer that much damage?
