If your order did not go through as intended for whatever reason and you need a refund, you may request one on your Apple Pay payment just like any other sort of payment. Unlike cash, the returned money may not appear in your account balance for a few days. You must also obtain McDonald's authorization for the return beforehand. They will only allow payments for orders that they are aware were incorrect. If you just did not like the order, they may refuse to issue a refund. If someone uses your digital wallet without your permission, you must contact your banking institution. However, because someone must utilize your phone's security safeguards to obtain access to your mobile wallet, any fraud accusations may be difficult to prove.
