Apple does not do support by email.
Refer to this page for Apple Support for different countries ➔
Choose your country or region - Official Apple Support
Select your country (if you do not see your country, also look for "other" in regions; e.g., "Other Africa"), then "Choose a product". Click the "show" item under each category for more selections. 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.
Check your information in Contacts. You could have several entries.
