Should I leave negative feedback before the case is resolved?

[bullnutt]

Hi,

I bought an item that was described as being in "excellent" condition - it isn't, it's broken, and upon investigating the product, it has been inoperable forat least 3 years. The seller either didn't test the item before sale, or did test it and decided to ship a broken product anyway.

eBay have placed the case "on hold" for another five days.

Meanwhile, the seller has not responded to me, yet has listed two new items (and sold one) since.

My question is this: do I leave negative feedback now, or once the case has been resolved? I feel an obligation to warn buyers of his listed items of my experience, and that I don't believe this seller is trustworthy. However, I'm not sure if leaving negative feedback while a case is still open is either helpful to my case or advisable by eBay.

Any feedback on this will be appreciated.

Cheers.

TLDR: Bought item, it's broken, seller won't co-operate, eBay delayed case, do I leave negative feedback now or once case has been resolved?
