Not sure who you talked to at eBay, sadly you do sometimes receive the wrong answer. You need to contact them again, as they should provide you with the correct label, and charge it to the seller's account. If you pay the extra, there will be no way to reimburse you for the amount you pay.
I strongly recommend contacting Customer Services very first thing in the morning when the lines first open, as 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 between 8 a.m. to 10 p.m. on weekdays.
9 a.m. to 6 p.m. on weekends.
As said, I recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
