It's Ok - I am not in desperate need but thought I would share as he is SUCH a cock and it's kind of funny 
I bought and paid for something which I thought was suitable according to the listing. It was not at all clear what he meant in the description and overnight it occurred to me that he might have meant something different.
So I messaged in the morning to ask for clarification. He wrote back saying it wasn't what I had thought, and he could always relist so let him know.
I wrote back straight away saying 'Oh yes I am so sorry but if that's the case, yes please, this item won't fit'.
Heard nothing till late afternoon when he sent a partial refund and a message saying 'well an email would have been nice, still waiting to hear from you so am keeping some of the money' basically.
I was like, wtf, so I messaged back really politely saying I had replied, and could he check his ebay inbox as sometimes emails don't come through from ebay.
No response.
Waited another day and emailed to ask him why he had kept some of the money. I explained about ebay refunding FVF etc.
I got a RANT in reply - apparently he had been concerned about this aspect and though I had told him he need not worry he was still keeping the money - also he had booked a courier and had to cancel that - etc etc. And if I dared to think about negative feedback he would 'do the same'
tbh I'd been thinking positive till now as he is new to ebay and clearly confused.
So I emailed back apologising AGAIN and explaining that I hadn't incurred him any fees, (would have been willing to pay initial listing fee of course, should he not sell on relisting) and saying that if he didn't refund the money I would need to open a case, and would rather have kept things amicable.
I got a reply this morning. He had already sent the item apparently (was paid for around 7pm the night before and he had offered to relist it at 11am the next day) and had had to 'recall' it from Hermes. 
Like, they do that.
He did sound embarrassed though and said 'will have to pay them something so lets just leave it at that'.
I really, really want to email back saying BOLLOCKS. But I won't.
