What happened?
I redeemed a Claude Pro gift subscription. The redemption was confirmed
successful. Shortly after, my account was silently downgraded to the Free
plan with no notification or action on my part.

Billing page evidence:

• Current plan shows: Free plan
• Invoices show: $0.00 × 2 (Mar 5, 2026 and Apr 13, 2026) — both marked "Paid"
• This confirms the gift subscription was recognized by the system

but the plan entitlement was not maintained.

Support contact history:

• Contacted support via email multiple times
• Fin AI Agent (Anthropic's support AI) confirmed this is a technical

billing issue but stated it cannot escalate to engineering or restore access

• Conversation ID: 215474017024498

What I expected:
Account should remain on Claude Pro for the full gift duration.

Request:
Engineering team to verify gift redemption status and manually restore
Pro plan entitlement for remaining gift duration.

What Should Happen?

My account should remain on Claude Pro plan for the full gift subscription duration. The plan entitlement should not be silently removed.
