Birth Certificate date/name does not match with passport

[b1t]

Hi
I received a RFE asking for my birth certificate.
My BC has a different date and name on it than on my passport.All my other documents match with the passport so I put in that date and submitted the forms.
Now they want the BC or NABC?
My place of birth is in Sierra Leone; I cannot go there to get a NABC.
Please help!!!

Why does your BC not match what's in your passport?

You need a good explanation of it.
