I would offer a partial refund yes. Unless she is near enough for you to go and collect the items.
China, glass etc just not worth the bother of an inexperienced packer returning it.
I used to restore antique dolls and so I had a couple of minor incidents - once the eyes I had reset came loose in the post, the buyer panicked and made an almighty fuss - eventually she insisted on bringing the doll back to my house for me to repair.
She was a very bossy older lady and I think the more I tried to explain and offered to pay for her to get someone local to put them back (quite a routine job) the more she wanted her own way.
It's something in the thing about wanting to be heard, wanting 'justice' I think - the genuine scammer is somewhat rarer.
I also had a buyer who won a chair for £10, which I wouldn't let her arrange a courier to collect (as per listing - she ignored that part) and she went on and on and got more and more patronising and demanding, and I just did the resigned, calm, 'look you have 120 feedback, I have over a thousand, so I know the way it works. I'm not going to sell it to you, and I am sure you will leave me negative fb like the other poor sod you negged for the same issue a while back, but the chair is going on the bonfire once I have removed my son's lego from the back of it.'
I never did get a neg after that, or hear from her again.
