What's Wrong?

My Claude Pro gift subscription was automatically downgraded to Free after only 5 days, without any action on my part. Invoice confirms the service period is April 4 to May 4, 2026. Support chat (Conversation ID: 215473834680943) confirmed this is a billing bug but was unable to escalate or fix it. No email response after 6 days. Related issues: #44163, #45335

What Should Happen?

The Pro gift subscription should remain active for the full gifted period (April 4 to May 4, 2026). The account should not revert to Free until the gift period expires.
