Hello Sir,
i have been facing a very similar issue. Had ordered an iPhone 6 from eBay on 23.04.2016 for Rs. 40000 and was sent a second hand phone which stopped working within 20 minutes of switching it on. Raised a claim on 9th May. No update till date.
Being a lawyer, I intend on taking strict legal action against the wholw eBay team.
Kindly let me know if you're interested in joining hands for the same.
