I am not showing to have the 100$ promo credit. Can this be fixed?

I am not seeing the 100$ credit for signing up. To be honest I did create this account with the promo almost 1 month ago(after watching youtube). I am now ready to use Linode but did not see the 100$ credit still after logging back in today, I learned of Linode and the promo from a "tech youtube" and I clicked his link to make the account. If it is because I created the account and did not use it for a month, then I understand this is my fault. I am just wondering if it's possible to still receive the promo? If not I understand

Thanks
