Buyer visit our listing and than he checks payment option and than he buys item online that means he accepts all the terms mentioned on listing.
Than why seller are under threat of negative rating if he doesnt offer one or other payment option which buyer wants and at last never pays.
In such cases negative feedback should be removed becuase buyer wants something which is not as per terms of sale,instead this buyer is subject to legal action because he doesnt complete the order.
And intelligent ebay team should take him to the court.
