Is there a number to contact Apple support in West Africa, Nigeria?

The list Contact Apple for support and service - Apple Support shows only two phone support numbers in Africa: Egypt and South Africa.

Apple has a page for finding service support on their Nigerian webpage: Find Locations - Apple. This has links to sales (Apple Authorized Resellers) and Service & Support (Apple Authorized Service Providers and Online Support)

Or you could try using the Get Support link at the top of this page.

No, sorry.

But you can reach to -> Apple Stores In Nigeria And Their Contacts Address:
