Contact eBay Customer Service they should be able to provide for you the correct label, and charge it to the seller's account. I do strongly recommend contacting CS first thing tomorrow morning not now, but at 8 a.m. that's when ' live agents' are on duty, and then, there's more chance of Dublin answering.
This is the easiest and quickest way to contact eBay Customer Services, for a Call Back option.

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.
As said, I recommend contacting CS first thing in the morning as there's more chance of Dublin answering.
