I'm sorry to hear that a payment that you sent is on hold. If there is no transaction in your PayPal account, it sounds like you used a card to pay as a guest rather than log in to your PayPal account. Otherwise, the transaction would be in your history.
If the seller's seeing delayed funds availability for the transaction, they can add tracking that shows delivery in order to have access to the funds more quickly.
I hope this helps!
