I’ve been waiting over a month for Anthropic support to respond to my billing issue

In early March, I noticed approximately $180 in unexpected charges to my Anthropic account. I’m a Claude Max subscriber, and between March 3-5, I received 16 separate “Extra Usage” invoices ranging from $10-$13 each, all in quick succession of one another. However, I wasn’t using Claude. I was away from my laptop entirely and was out sailing with my parents back home in San Diego.

Nick’s Thoughts

I tried their Pro plan on March 1 and immediately noticed how bad their usage limits were, so I asked for a refund that same evening.

Their chatbot accepted the request, I was downgraded to the free plan immediately, and since then I have been waiting for the money.

Issue a chargeback.
It's important to remember that a chargeback should be considered the nuclear option, and, when using it, one should be comfortable with the possibility that one might never do business with this company again, since it could result in being blacklisted (even if one is, in fact, in the right). I'm not saying not to do it, but one should keep in mind the potential repercussions.

I always wondered about this. Do companies tie the credit card to an identity to block or do they just block the cc number?

If the latter, seems like a small friction point for a consumer. Given how often cc numbers change and how many an (American) consumer has, this won’t block anything unless you are charging back more than once every few months.

Except the banks have "helpfully" provided a service to merchants to tell them, "this card has expired, here is the new number to charge" (or expiry/CVV).

I remember getting into an argument with a bank teller about me wanting to block/dispute transactions and how they kept approving transactions. "But you have an agreement with the gym..." That's between me and the gym, not for you to facilitate on their behalf.
