these are user forums. we can't help you other than make suggestions.
"adobe" is a large corporation. who in adobe issued the voucher? you should contact them.
in the future, to find the best place to post your message, use the list here, https://community.adobe.com/
p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post if it helps you get responses.
i'm not even sure of the correct forum for your question. it's sure not this one, though. you can try https://business.adobe.com/products/magento/community.html, but searching via google might lead to a better site.
