Except for the fact that you specifically say "IDs" in the plural, I would say you were using the same Apple account. Since you are not, you may need to contact Apple to resolve this.
Refer to this document for ways to contact Apple ➞ Choose your country or region - Official Apple Support
Select your country (also look for "other" regions), then a product. If you don't see one that handles your issue then keep experimenting with selections until you reach one that gets you a chat session or a telephone call and get the representative to redirect you.
