Anthropic users say billing spike went unanswered by support for more than a month

The charges

It has been reported that a Claude Max subscriber discovered roughly $180 in unexpected "Extra Usage" charges after receiving 16 invoices of about $10–$13 each over a two‑to‑three day span in early March. The account owner says they were away from their laptop — out sailing with family — and that the usage dashboard showed a session at 100% despite no activity; Claude Code history allegedly recorded only tiny sessions totaling under 7 KB. Other Max plan users have reportedly described the same behavior on GitHub (claude-code#29289, claude-code#24727) and on r/ClaudeCode, where posts point to inflated usage meters and a flurry of extra charges.

The support experience

The account holder says they emailed Anthropic support with evidence on March 7 and, within minutes, received a canned reply from “Fin AI Agent, Anthropic’s AI Agent,” directing them to an in‑app refund flow that only applies to subscriptions — not Extra Usage line items. They asked for a human to investigate and allege they received no substantive follow‑up despite multiple reminders (March 17, March 25, and again a month later). It has been reported that the author still hadn’t heard from a human responder at the time of their post.

Why this matters

This is more than one annoyed customer. Billing discrepancies are concrete money lost — and trust erodes fast. The larger pattern here dovetails with an industry trend: companies lean on AI to scale support, sometimes to the point where a human seems unreachable. Is that progress… or a bug? For users, the heart of the story is simple and emotional: you don’t want to be billed while you’re on a boat, and you certainly want a human to look at your account when the numbers don’t add up.

Anthropic has not been quoted in the post; the company has an opportunity to clarify the cause, fix any meter errors, and reassure customers that AI assistance won’t become a permanent wall between people and problem‑solving.
