I want to change my bank details for payouts but it says I need to confirm the change by entering the old account number in full. This is an old account and I can’t remember the details (it was closed down)?
If you can remember which bank it was with contact them and ask for the details. Otherwise contact ebay in the morning and see what they suggest. You can request a callback on here: https://www.ebay.co.uk/help/eua?id=5275&mkevt=1&mkpid
