Happened to a close friend of mine. A bit of digging revealed the same pattern with fraudulent gift purchases for several other people before I stopped looking. They were also being ignored by Anthropic support. One since January.
Apparently they're so short on inference resources they can't run their support bots. Maybe banning usage of Claude Code with Claude will allow them to catch up on those gift fraud tickets.
Took a long time for me to reach this level of scathing. It is not unwarranted.
“Hi Anthropic Support,
I'm a Max plan subscriber and I'm writing about approximately $180 in unexpected Extra Usage charges that appeared on my account between March 3-5, 2026. I attempted to resolve this through your Fin AI chatbot (Conversation ID: 215473382652967).
Here's the situation: - I received 16 separate Extra Usage invoices between March 3-5, ranging from $10-$13 each, all charged automatically. - I was not actively using Claude during this period — I was away from my laptop entirely. - When I checked my usage dashboard, it showed my session at 100% usage despite me not using the product. - My API usage dashboard shows only $70 in total lifetime usage, confirming this is not API-related. - My Claude Code session history shows only two tiny sessions from March 5 totaling under 7KB — nowhere near enough activity to generate these charges.
This appears consistent with known billing/usage tracking issues reported by other Max plan users (GitHub issues #29289 and #24727 on the anthropics/claude-code repo), where usage meters show incorrect values and Extra Usage charges accumulate erroneously. However, it is possible that my account was compromised, and I would like assistance determining if that is the case (or if it really is a bug.)
Either way, I am requesting a refund of the Extra Usage charges from March 3-5 only — I do not want to cancel my subscription.”
When a third party leaked my CC number which then was used to buy Spotify premium, all it took was 10 minutes of chat with a very polite support agent to have it resolved.
Ignoring the customer is not going to fix it. They'd know if they asked Claude.
