Nothing eBay can do now, as they do not offer warranties or guarantees on items, just that they are just as described on receipt. If they are not, a buyer has 30 days under eBay's 30 day MBG, Money Back Guarantee policy, to return the item for a full refund.
There are only 60 days in which to leave feedback.
If you bought this from a Private seller you are too late to claim a refund. You could try your payment provider, though not sure of their response if the item has been in use, albeit irregularly for over 2 months.
If purchased from a registered UK business, who offered a guarantee and is now not upholding this, then as I don't know the value of this item, or if it's worth your time, but you can turn to Citizens Advice for your next steps, if you wish to take this further.
