My name is Zach and I'm the Director of Support here at DigitalOcean.
I'm reaching out to you regarding the GitHub Student Developer Program. We were contacted by our partner GitHub and they've indicated to us that they have revoked your membership in the program.
While we love supporting the entire developer community, this particular program is only available for students eligible as determined by GitHub. Similarly, it has always been our policy to only allow one promo redemption per account. As such, to make it fair across the board for all users we'll be removing any extra promo credits from your account and want to provide you with an advanced notice.
As a token of our appreciation for your understanding we did honor a portion of the credit that you've redeemed.
Thanks again for being a great DigitalOcean customer! Happy coding,
