Default [Q] HTC One Charging Port Damaged

Hi Guys

So I bought an HTC one, international version two months back from eBay India. (It has no warranty)
Recently, the charging port on the device has malfunctioned. HTC won't replace it for obvious reasons
and my seller has no hardware warranty. Is there a way in which I can get it repaired/replaced.
All suggestions are welcome (Even do-it-yourself ones).

Thanks
