Photography Plan giveaway for Stock Contributors – expired code in contrary to what the email states

I received a complimentary Creative Cloud Photography Plan back in 2018 which I haven't redeemed since I had been using Adobe CC as part of a team and I didn't feel the need since the email clearly stated that I had until July 2021 to redeem it. Now that I am no longer part of that team I would have liked to redeem that code but it returns a 'This code has expired' message. What to do now? The redeem page doesn't have any help links, the giveaway FAQ is a dead link and Adobe Stock support just won't load.
