Didn’t send eBay item in time and postage label has expired, is there any way to renew it?

[VanillaImpulse]

I’ve been so busy with work and assumed I’d have about 5 days to post like Vinted, didn’t realise it was only 2 with eBay. I sold something and now the Royal Mail postage QR code has expired as I was supposed to post by Thursday. Is there anything I can do to sort this?

I believe you can just apply for a refund with RM, within 14 days of the date it was supposed to be posted by.
Edited to say: Sorry but i just double checked and not sure if it’s the same if you got it via Ebay.

First of all contact the buyer and apologise profusely!
