I've been waiting over a month for Anthropic support to respond

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.
