Answer:
Dear [Mrs./Mr./Ms.] *Name Here*,
This is *insert own name here* from *insert class and grade here*. I would like to inform you that the "statement of result" that I received spelt my name incorrectly, and I would like to receive a new copy that has my name spelt right.
Having the wrong name could cause issues in the data base, as well as future grades. I hope you and the staff can fix this issue soon.
Wishing You Well,
*Insert own name here*
