Can you enable the 50% discount for my old account?

I just created another account for a foundation I run and was able to upgrade (which I did) using a 50% off code. Is there any way you would honor that discount for this account as well? I need to upgrade this one too. Thank you!

Kindly note that your account "Walsh_Allison" was created more months ago, and the 50% welcome discount is meant for only new accounts.

This means, unfortunately, we can't enable the discount for this account.

Your understanding is most appreciated.
