Ticket-deflector — Triage a refund-after-cancel support ticket
Classification: (b) escalate to billing — duplicate-charge after a cancellation requires a finance review. Draft reply (held for billing review, not sent): Thanks for flagging this — I'm pulling the cancellation and the new charge now so billing can confirm both in one pass. You'll get a refund + a written confirmation that the Starter plan is fully closed within one business day.
