Dust billing issue: canceled Pro plan, lost access, and unresponsive support

Hi everyone. I am reaching out because I have had no response from Dust support since October 11, 2026, and I urgently need help from the team. My workspace is monclus.benetreau. What happened: I consumed my Max plan credits, selected the Pro plan on October 10, and the next day I received an automated cancellation notice I never requested. My access was removed and I was charged 821.29 EUR (Invoice 8D6A9AF8-67918) for a service I could not use. I had to pay an additional 36 EUR today to regain access (Invoice 8D6A9AF8-68083). I have sent several emails to support@dust.tt with no reply. I am asking for urgent escalation to a human member of the billing or support team. Thank you.
