What's with not being able to leave negative feedback for a dodgy seller?

Can't leave neutral or negative feedback for a bad seller why?

More information is needed...is it still within the timefram to leave any feedback?

If they are a power seller you have to wait a week to be able to leave neut or neg feedback.
