Oops, we had a technical hiccup

Later could mean hours later or seconds.
Have you tried repeating the attempt immediately?

 

You had 30 days from the last estimated date for delivery to open your Dispute, but the time for escalating it to a Claim and getting your refund is a matter of days (seven I think?) after the escalation.

 

You may have been too patient. If the Dispute/Claim times out, eBay assumes you were satisfied and the transaction is ended.

 

But.

You have 180 days from payment to open a dispute on Paypal, as @richardcm  says. The PP Resolution Centre is at the top of your PP account page under Tools.
