Didn’t received purchase or receipt, money deducted from account

I was making a purchase in fortnite and I clicked to buy it then used my typed my password, as it went through it denied and said I had insufficient funds but I had checked before having more than needed to purchase it, so I went to my account and it had deducted funds and I went to go check my fortnite account and there was nothing, I went to my Apple ID for a receipt but nothing came. I knew that receipts usually come later but after 2 hours there was nothing. Please someone help me.
