Is this a fair amount for a partial refund?

Sold iphone on ebay last week but ended up in hospital and my boyfriend said hed post the phone but never did and so its still not been sent as i just got home and been seriously stressed due to the weeks events as well as upcoming court case where i have to give evidence against my boyfriend and hes telling me not to turn up, which already got me in trouble before (i'm not sure i should even be calling him my boyfriend anymore, pretty sure i'm done with him).

anyway i explained this all to the buyer and that i hadnt refunded her yet because she rushed into paypal dispute which meant paypal emptied by account… Anyway i said i was really sorry and if i could do anything to make it up to her then let me know, and she wsuggested a partial refund and phone sent for her to receive tomorrow (which would require me paying more to get special delivery)

i asked how much refund and pointed out that i'm skint thats why selling phone and she suggested £20… I pointed out that meant id be selling it for the same price i could get it on Buyback in Cash Generator except if i put it on buyback i could actually get it back when less skint so that would be a better choice for me but that i knew that would be a bit selfish so i suggested £15 because even £15 was a lot of money to lose when i'm skint and still losing the phone too…

she got all huffy like 'i understand you may be skint but i have paid for this phone and expect to get what i have paid for… ' etc and i'm a bit gobsmacked… Surely when she's asking me to give er the phone AND £20 of her money back then its not quite what she originally paid for

as much as i genuinely felt bad about the delay to begin with i'm now shocked by her attitude when i at least was willing to give her the phone AND lose out on £15 which i still think is excessive for the actual realistic level of inconvenience this would have caused her, nothing more than being impatient and i was in hospital so it was hardly something i could control so it seems a it unfair that i should lose so much money…

so i'm baffled by her attitude like she's entitled to the phone and £20… Especially when she's also demanding it be sent for her to receive next day which costs more than she paid for postage! So can someone please tell me honestly who is being unreasonable because if its her then no way i'm sending her the phone and refund but also if its actually me being unreasonable then i don't want to be so i want to know and i'll give her the phone and partial refund

Good luck getting someone to read that novel.

If you didn't ship the phone just honor the refund. Close the case. Move on and sell it to someone else.

No, If she's opened a dispute DON't YOU REFUND HER. And don't send the phone. Paypal will take the money from you once the dispute is settled.
If you send her the phone, and also give her £20 back, you will lose both.
Now you should deal with Ebay, and not her directly…
