What's Wrong?

On March 22, 2026, while creating a Team workspace, I encountered error code 15WQOCG. The UI displayed an error suggesting the workspace creation had failed. I attempted to create the workspace again — it succeeded. However, the first workspace had also been created and billed silently in the background, resulting in double billing.

Impact:

• Two Team workspaces were created and billed for the same account
• - Organization 1ea9fe22-b13a-40a6-b2f5-1d41cb03eb69 (intended, active)
• - - Organization 80b881a5-2144-40d0-885a-41f519918951 (duplicate, cancelled immediately)
• - - - Despite cancellation, charges continued on the next billing cycle (April 1)
• - - - - Total erroneous charges: over CA$600
• - - - - - Invoice references: HEC5B9DM-0001 (legitimate) and R4FSXVKT-0001 (duplicate)

Support experience — 30 days, zero human response:

1. Four emails to support@anthropic.com — only automated bot responses
2. 2. In-app support tickets (Conversation IDs: 215473999554323, 215473999729250) — bot only, no human transfer despite repeated requests
3. 3. Bot (Fin AI Agent) gave contradictory response: claims both that "a refund has already been provided" AND that the account is "not eligible for a refund" — in the same message
4. 4. Bot refuses to transfer to a human agent and loops endlessly on the same scripted response
5. 5. No phone number, no live chat with a real person, no escalation path available

This is a billing platform bug, not a user error. Error 15WQOCG should not silently create and bill a workspace while showing a failure message to the user.

What Should Happen?

Error 15WQOCG should not silently create and bill a workspace while showing a failure message. Cancelled workspaces should not generate new charges. Billing disputes should be handled by a human within a reasonable timeframe.
