eBay do not answer emails.
Contact them as below for them to review the case as you should have received a full refund for an item not as described if you claimed within 30 days of the item's last estimated date for delivery.
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.
I recommend contacting CS very first thing in the morning, when the lines first open, as there's more chance of Dublin answering.
