You are way, way too late to claim any refund from eBay who have a 30 day MBG, Money Back Guarantee policy for items not as described, and if this was a case of doesn't fit, sellers also have a timeframe for the return, for example 2 weeks.
You are too late to claim anything from your payment provider too.
If they have your money and your item, it's a legal route now to take, if you wish to take this further. However, it may cost more than the item in question. 🤔
