Thank you for your help. I got my refund today 

I lodged INR this morning and got my refund like an hour later. Ebay said the tracking info the seller provided was not valid (just what I thought so) But I don't have any option to leave feedback now.. Why am I unable to leave feedback? I really wanted to leave this seller a negative feedback so other buyer doesn't get scammed like I did

Unfortunately, you only have 60 days to leave feedback...

The seller has utterly horrible, horrible feedback

82.6%

and it has been horrible for a year at least

And you still bought off them

Just like other buyers will continue to choose to buy from them, with or without your feedback being there
