Feedback for faulty item and unpleasant seller.

[mcbg1160]

If I buy a product that is faulty but the seller implies I'm lying so no return, how can I then give negative feedback to warn others?

And then leave appropriate feedback without mention of "case" "Refund" return" "EBay" and so on. 

"Seller was unhelpful in resolving problems" might do
