If you bought the postage from eBay this will explain how to receive a refund for the unused label, you may need to wait 24 hours for the label to appear before being able to void it.
Find your label with this link . https://www.ebay.co.uk/ship/lmng/labels-history/seller-hub and to the left of the sales record there is a drop down menu under 'Actions' click on that , then click on 'Void Label'.
The refund will take between 5 - 21 days to process.
If you cannot manually change the new tracking number , you may need to contact eBay Customer Services for them to do this for you.
This is the easiest and quicket way to contact eBay Customer Services, for a Call Back option.

Lines open between 8 a.m. to 10 p.m. on weekdays.
9 a.m. to 6 p.m. on weekends.
I recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
