亞馬遜買家要退貨（3月買的產(chǎn)品），但是他不想出運(yùn)費(fèi)，還威脅我，好氣人啊！

買家在3月份買了一個(gè)充電器（61美元），前天（8.1）跟我說充電器充不了電了。我跟廠商聯(lián)系，他們很愿意幫忙，說要把充電器收回，檢查下具體問題才行。我跟買家說了，他不肯，我就讓他把貨退到我這邊，但是他要出運(yùn)費(fèi)（畢竟他的退貨請求不符合政策）。然后他就炸毛了，說：
“Thank you for your prompt response however, this is not satisfactory. I will not spend any more time trying to rectify this situation with you or the manufacturer. I will however spend any number of hours leaving negative feedback, creating a YouTube video with full descriptions of the problems and perhaps I will spend the shipping charge you required to buy a domain name reflecting your amazon account and post my story there as well and making sure it hits the top of search engines as that one of many things i excel at. I am trying to replace this defective unit which has cost me around 200 dollars. I am the kind of individual that will spend hours and weeks rectifying what i feel to be injustice. If you wish to change your position, i will refrain from action for 24 hrs.”
他說會把這件事做成視頻放到油管上，這簡直是赤裸裸的威脅！我可以接受他的退貨，但是他這樣做就太過分了。。?！，F(xiàn)在咋辦？
