Buyer wants a refund after not reading description properly and rushing to bid?

[jackgibbs24]

Hi all,
Recently someone purchased an iPhone XR I had that is locked to an iCloud account (I bought the phone off someone on eBay recently without knowing it was locked permanently. I'm not very good with phone technology and bought it not knowing I wouldn't be able to unlock it). I decided to simply resell the phone at a low cost in auction on eBay. I tried my best to describe the condition. Something along the lines of noting that it was 'locked and I didn't know how to unlock it. Someone told me that perhaps it could be unlocked with software or online but I do not have any knowledge on this. I bought it recently - but am selling it again because of this problem... etc etc'. 
The person who bought it made a bid at the last moment and judging from his early messages he didn't read the description. Initially saying he made a mistake by 'perhaps being a bit too quick to buy it', that he would try and get it unlocked himself and we would move on. Then recently he sent a message saying that he didn't have any luck with unlocking it, and that the item description is not exactly clear on it being an 'iCloud activation lock' - something I had no idea existed. I simply knew the phone as being locked. So now he is requesting a refund and threatening an eBay dispute. 
If anyone could help with advice - who would be the winner here? I will refund it if I have to (after listing the item as non-refundable), but I would really rather not - as I already put the money towards buying a different phone & simply don't really want to have to go through auctioning it again.

@jackgibbs24,

Until or unless the buyer opens a not as described dispute there is not anything you can do except tell the buyer to ship the phone back on their dime since the information about the phone being locked was in the description, and it is not your fault that they did not have time to ask questions.  

If they open a not as described dispute, it will likely be handled through ebay's automated dispute system. Since you have 3 working days to respond, call ebay's customer service, when you reach a rep ask them to review the messages between the buyer an you. (it will not matter if you have deleted them they are still in ebay's system) point out where the buyer says  "he made a mistake by 'perhaps being a bit too quick to buy it".  That may be enough for the dispute to be closed in your favor or the buyer being told to return the item for a refund of the item price only.
