Many members received these ' Safety Recall' messages months after an item has been in use.
Unfortunately, as you purchased the item in October, you are too late to claim any refund through eBay's 30 day MBG, Money Back Guarantee policy.
Did you by chance buy from a registered UK business who offered a guarantee for this item? You'd need to then chase this up outside eBay.
Buying from a Private seller , there is no recourse here for a refund, you can try your payment provider, worth a shot, but not sure how successful that avenue can be.
