(seller on eBay) sold me a “Demo” phone

[dhruv1989]

Hi all,

*** is a seller on eBay who is engaging in fraudulent and illegal activities and selling “Demo” phones. I was informed about this when I contact Oneplus technical support as my device was giving a lot of problems for past several months. 
Any suggestion on how can I go about getting this reported and starting a refund request. I purchased this over a year back.

It is much too late to request a refund.  The eBay guarantee is for 30 days after receipt.  Most credit cards can help for 90 - 180 days.

It is also too late to report the item you purchased.  You could see if he has any similar items currently listed, and try reporting one of those - every item has a report link on the right margin.
