We are not eBay but members like yourself.
You need to contact eBay Customer Services and explain what has happened here, but you have no tracking to prove the item was collected.
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.
I strongly recommend contacting CS first thing in the morning as there's more chance of Dublin answering.
