' eBay say it's too late', but who did you speak to at eBay Customer Services ? Unfortunately, one can receive different responses from different agents.
I do recommend trying them again, there's nothing to lose, but do so only very first thing in the mornings of next week, when the lines first open at 8 a.m. 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.
