I can’t buy coins on CODM from my appleiD which I have $30 in it

Are these purchases using the Apple in-app purchase mechanism, or is this using some other purchasing system within the fame or at the game website?

An Apple Account can usually be used with an in-app purchase, but cannot be used with non-Apple purchasing mechanisms.

What you can buy with your Apple Gift Card or Apple Account balance - Apple Support

What are you trying to buy, and happens when you try to buy something with your Apple Account?
