B) I've already paid and received a notice that the card was processed, however I haven't received a receipt from Apple or the item I purchased:
Please go to your phone's settings and tap your name, then tap iTunes & App store > Apple ID > View Apple ID > tap Purchase History. Look to see whether or not the purchase in question is on the list. If it is not there, or it is there but you have still not received a receipt and the purchased item after more than 24 hour since the purchase date, please use this page to contact Apple Customer Service.
