If you have paid, you will have an email from Ebay giving an estimated delivery date.
If the item you have bought doesn't arrive, then one day after the latest estimated delivery date, you can open a case saying you have not received the item.
"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
