First, check if the problem indeed is at Apple’s end of things and if there’s an issue with Apple's servers: Apple - Support - System Status
If you still have problems, contact official Apple Support:
Click here --> Choose your country or region - Official Apple Support Select your country, 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.
