Ok... ?

As I understand your concern, your location is North Caroina, that it is not near Temu, Ghana, and that you were not attempting to log into Facebook from that location with that device at that time. Is that correct?

Did you follow up with that Facebook service to gain some insight?

I provided some details and asked some additional questions that you have yet to answer. Until then I still do not fully understand your concern.

If that was not you then take the appropriate actions with your Facebook Account. Don't click any links in that email (or any other).

I do not quite understand that question, but if you are using a VPN, don't.

Writing an effective Apple Support Communities question - Apple Community may help you to compose a question others may understand so that they can better assist you.

Were you in or near Tema, Ghana when attempting to log in?

I understand your question, but you are not answering any of mine. If you want to address your concerns you need to act upon them.
