When they issue the cancellation on ebay a refund will be issued. If for some reason they don't do that you'll have to wait for the last estimated delivery date on the listing to pass then select "Report an item you didn't receive" on here: https://www.ebay.co.uk/help/buying/returns-items-not-received-refunds-buyers/get-help-item-hasnt-arr... and escalate it 3 complete working days later to get a full refund.
