He bought 6pcs with 3 id,we honest report battery problem and refund all he paid.He soon left negative feedback.But he ask we give him 15USD/per discount for every item he bought if we want to revise feedback. 2days later,the amount he required become 20USD/per. How Greed he is!During the period,he indicates us to communicate on skype for several times,not on ebay. We found that he also left many negative feedback for others,many feedback was revised by he.During the past several years,he always do such evil things to others.
