While I don't know what F/book eBay is if you bought on ebay the summary will have a latest date for delivery.
If the item is coming from abroad that will be some while.
When that is past [possibly now] you open a non-receipt case in the resolution centre [link below] and - if seller does not refund - escalate after 3 days. Ignore any suggestions to wait longer.
