Appeal for Scholarship Retrieval - how to start writing an appeal letter?

Hello All,
I have been offered a scholarship however, due to not responding on time, the scholarship was re-assigned to a person on the Reserve list. I did not receive the scholarship acceptance EMAIL that they had originally sent and did not withdraw my application. Could you please help me with writing an Appeal letter? and provide any advice you have please?

Appreciate your help ASAP.

THANKS!

Draft what you think is important to include in the letter (your real reasons why you missed it etc.).

We're all here to help you :)

Please guys, check my work.

Your comment doesn't help the student. Please make sure to post useful posts instead. Thank you.

And you are...?

Nuni,
1> Write letter in this way.You are very grateful to them for giving the biggest oppurtunity of your life & how it was going to affect not only you but also your family/community/country as you have big dreams to fulfil.

2> Show your disappointment of missing the oppurtunity
3> Tell them the reasons of not responding the authority
4> If you would be reconsider to what extent you will go & reach the apex
Guys am I correct?
Thanks
