Buyer requests refund on ebay - underhand?

[AnneShirley18]

I'm not sure why I'm so wound up by this but i can't sleep so here goes.
I sold some clarks shoes on ebay -in excellent condition. UK size 8 ladies.
A potential buyer messaged:could you tell me if these are 41 or 42? I said I dont know. I just know they're a generous UK size 8.
That person won the bid. They asked if I would be so kind as to post them next day as they needed them ASAP. I went out of my way to accommodate.
Cut to today where I get a refund request. ZERO niceties. Straight in with a request because the item was not as described and buyer was disappointed to be misled by inaccurate "generous" description. Shoes do not fit.
I dunno. I just feel really hurt. There is an implication that I've been underhand which I don't appreciate. Buyers have commented in the past that I do myself a disservice by being overly descriptive when my items are great. I'm just a private seller not a business. Anyway she is fixated on the word "generous" in that message we exchanged. It's kind of subjective I suppose (surely she knows that too) but they are. If asking if they are a 41 or 42 I would say that since an 8 equates to 42 in the clarks size guide then they are a 42. Therefore, the more generous of the 2. When I used the word generous I also couldn't have known what the buyer was after when she asked 41 or 42. She could have wanted the smaller or the larger end of the scale. I simply gave a judgement so there could have been no attempt to deceive on my part. Clarks shoes do vary in size. It is a gamble buying them on ebay. I've been caught out before. I never considered it the sellers fault though, I simply sucked it up and resold them.
Basically ebay won't refund if something doesn't fit but they will if it's deemed to be an inaccurate description or pic. I believe she is being underhand so refund is more likely.
What upsets me is, ebay usually sides with buyer. Also what upsets me is that I went out of my way for her and actually if she'd sent me a nice message, we could have come to an agreement.
YABU: you wanted to fob off tiny ill fitting shoes on someone unsuspecting for the princely sum of £7
YANBU: she is being underhand and unreasonable

I've sold a sealed perfume on vinted some days ago.Today the buyer has collected the item and claiming that i sent an empty bottle of perfume and sent the pictures of an empty bottle.
I can't accept that as the box was sealed. The buyer have only good reviews and me aswell, so it is really strange this situation.

Agree with this. I used to sell loads of used kids’ stuff on there. Never again. So many scammers and cheeky fuckers have destroyed it. Plus I can do without HMRC thinking that I should pay tax on my earnings on there - eBay now send reports to them I think. Selling items for less than I paid due to having used them - so no tax due. Frankly I’d rather bin stuff now. My local charity shop is often not accepting donations, which is a real pain if I’ve made the effort to get there and carry stuff (can’t park outside).

@rnsaslkih HMRC would want tax on all applicable online sales if you have income above your tax threshold - and it isn’t just selling off your second hand property

In previous years HMRC could have called upon your sales, but it is from the last financial year that eBay, Vinted etc are required to report to HMRC if thresholds on the value or number of transactions are met - that does not mean you owe tax on them, I do because I buy for the purpose of selling for profit and have already used up my tax allowance

As you are selling your own second hand property at a loss then you would not have any tax to pay
