Dear sir,
My name is rizwan and I am buying a jbl wireless headphone on 31th july from the online site eBay.in and they give me the duplicate product. so I call the saller and file a refund on site so some days later the saller calls me and said for returning product to him and I send the product to saller by the courier and some days later eBay calls me and said your refund is ready and it will be send on your location.
And they send me the dd . But it's returned by post office so I call customer service and told all story so they said we will working on it and it will be resend on 15 days but every time they repeated the same thing and the three months is passed away and they didn't give me the refund.
So I request you sir please give me my money from them
