Request for correction of a subject on my O Level Verification letter

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),
I am kindly requesting you to correct my verification letter of 16th/03/2020 in the names of Isabirye Emmanuel of index no. U0018/314 who sat for Uganda Certificate of Education in the year 1983.
The correct subject is Commerce instead of Geometrical & Building Drawing.
I will be grateful when my request is given consideration.

Yours faithfully,
Isabirye Emmanuel
