You should still be able to do so.
You can also, if you wish, contact Customer Services explain the order was cancelled without you're consent and you were disappointed not to receive your item. They will place a damaging defect on the seller's account. eBay do not like disappointed buyers.
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 recommend contacting CS first thing in the morning as there's more chance of Dublin answering.
