If you cannot add your tracking from Orders >> More Actions, you will need to contact Customer Services again, for them to add this number for you. If it's not possible, it's a minimum 14 days wait for the release of this payout.
Contact CS now, lines just opened for live agents, and there's more chance of Dublin answering first thing.
This is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.
https://www.ebay.co.uk/help/eua?id=5275&mkevt=1&mkpid
Lines open 8 a.m. - 10 p.m. on weekdays
9 a.m. - 6 p.m. on weekends.
Automated agents will be available on chat outside of the above hours.
I do recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
