What's Wrong?

Gift code: 28c373c8-bd84-4231-81b2-ae6ce2ae43db

Timeline:

• Had active gifted Claude Code subscription until June 9, 2026
• Friend purchased a new $100 Claude Code gift on June 6, 2026
• Attempted to redeem while previous subscription was still active
• Redemption failed, but code was marked as used
• Previous subscription ended June 9 — account is now on Free plan
• Code still shows: "Gift no longer available. This gift code is no longer active."

Troubleshooting completed:

• Cleared cache and cookies
• Tried incognito window
• Correct account, web only (not mobile)

Support interaction:

• Contacted support@anthropic.com — confirmed it's a backend issue, but unable to resolve
• AI agent acknowledged manual backend intervention is needed

Expected behavior: Code should be reactivated or replaced, as it was never successfully applied.

Similar issues: #66259, #48821, #45430

What Should Happen?

The gift code should be reactivated or replaced with a working code, since it was never successfully applied to my account. The account should be upgraded to the gifted Claude Code plan for the full purchased duration.
