Lost in a sea of scholarship appeals

I was recently rejected for a renewable four year scholarship. Their reasoning was that I didn't include my transcript, but I have a reliable witness who can claim that I included it in the envelope. I've seen multiple formatting for appeals, but I'm at a standstill because most, if not all, are for those that do not meet grade requirements. It's not the greatest formatting, but I'm looking for corrections and information I can include to help my case. Thanks in advance!

To whom it may concern,

My name is [My name] and I am currently a senior at [My school]. I am writing this appeal following a letter I received in the mail at the first of this month that stated I was rejected consideration for the Regents' scholarship due to no high school transcript being received. However, I am certain that the transcript was included with the rest of my paperwork. My counselor, [My counselor], was with me when I put the transcript in the envelope, sealed it, and I mailed it shortly after.

Hi! Here are some changes that I feel might be necessary..

I am writing this appeal following a letter I received in the mail at the first of this month that stated I was rejected consideration for the Regents' scholarship due to no high school transcript being received.

With reference to the (name of the letter/subject) that I received this month, It has been stated that the reason behind the rejection was due to the unavailability of my high school transcript. However, I am certain that the academic transcripts were attached along with the rest of my paperwork. In any case, my counselor [name], was present when I was mailing the letter. Moreover, she has already sent you a letter explaining her side of the story. Anyway, I am attaching a second copy of the transcript with this letter. I, therefore, request you to please consider me for this scholarship as I have put in a tremendous amount of effort to meet the eligibility requirements of the scholarship.

Please feel free to contact me in case of further queries.

Thank you for your time.

Yours sincerely,
