[BUG] Max 5x plan incorrectly downgraded to Free after Max 20x refund (Fable 5 government removal, June 13 2026)

Description

### Preflight Checklist - [x] I have searched [existing issues](https://github.com/anthropics/claude-code/issues?q=is%3Aissue%20state%3Aopen%20label%3Abug) and this hasn't been reported yet - [x] This is a single bug report (please file separate reports for different bugs) - [x] I am using the latest version of Claude Code ### What's Wrong? ## What's Wrong? Two compounding billing failures: 1. Accepting a Max 20x refund downgraded my account to Free instead of reverting to Max 5x. 2. Following support's resubscribe instructions charged me again ($106.60) — the system did NOT recognize my still-active Max 5x entitlement. ## Charge & Refund Sequence | Date | Event | Amount | |------|-------|--------| | June 4, 2026 | Pro plan renewal | $21.32 | | June 4, 2026 | Mid-cycle upgrade to Max 5x | $85.30 | | June 11, 2026 | Mid-cycle upgrade to Max 20x | $129.82 | | June 13, 2026 | Refund of Max 20x premium after Fable 5 removal | -$129.82 | | June 13, 2026 | Resubscribe to Max 5x (per Fin support instructions) | $106.60 | ### What Should Happen? ## Expected Behavior After the $129.82 refund (which only covers the Max 20x premium), account reverts to Max 5x. The $85.30 and $21.32 paid June 4 covers Max 5x through ~July 4, 2026 and is unaffected by the refund. No resubscribe or additional charge should have been necessary. ## Actual Behavior - Refund downgraded account to Free (no notification). - Support (Fin) instructed me to resubscribe, stating the system "should recognize your existing entitlement." - The resubscribe flow did NOT recognize the entitlement and charged $106.60 in full. - I am now paying for Max 5x twice for the same period ([$21.32 + $85.30] + $106.60). ### Error Messages/Logs ```shell ``` ### Steps to Reproduce Subscribe to Max 5x, then subscribe to Max 20x, then unsubscribe from Max 20x. ### Claude Model None ### Is this a regression? I don't know ### Last Working Version _No response_ ### Claude Code Version 2.1.177 (Claude Code) ### Platform Anthropic API ### Operating System Windows ### Terminal/Shell PowerShell ### Additional Information ## Additional Context - Billing cycle anchor: 4th of each month - Max 20x upgrade was made solely for Fable 5 access to use its full potential - Fable 5 removed June 13 due to a government-issued directive; refund accepted via offered flow - Fin chat: requested human escalation, Fin stopped responding before completing handoff - Follow-up email sent to [email protected]; replied requesting the human escalation Fin offered ## Related Issues Same entitlement mismatch pattern as: #47286, #48399, #49744, #54560, #61339
