My purchase was billed but didn’t give me what I purchased on my account

Recently while I was logged into my Xbox account on my ipad, i made a 20 dollar purchase of some coins in Minecraft, and at the time it did go through, but there was difficulty with the purchase switching to my device, not my account. The next morning, all
purchases had been lost, and I checked my email and there was a bill confirming the purchase. I have tried updating my iPad, logging in and out, and turning my system on and off, but was wary not to delete the app with the device glitch. Please help me. I
also checked billing Xbox account but it didn’t show anything at all.

TDLR ; Made a confirmed purchase on an account, it sort of worked for a night, then the next morning it vanished, but still billed me.
