Correcting my Name & Date of Birth on my UNEB Certificates

Response to this request is long overdue. By law, under all circumstances, Uganda National Examination Board (UNEB) should have responded by now (details). You can complain by requesting an internal review.

Dear Uganda National Examination Board (UNEB), my name is Kamal and I would like to kindly know how I can be able to correct my Name & Date of Birth on my UNEB certificates.
I'm soon gonna have an interview at the US Embassy as I'm planning to immigrate to the USA. They have asked me for my High school certificate(both UCE & UACE). But the problem I have is that my UNEB certificates have the wrong name & Date of Birth and I would like to kindly correct that problem before I go for the interview.
I have been to your Office in Ntinda, but you people are not cooperating and I haven't gotten any help yet.
Immigrating to the USA is once in a lifetime opportunity and I don't want to mess it up, so please help me on this issue

Yours faithfully,
Kamal
