$240 charged for annual plan by mistake — refund denied despite 0 usage

"Accidentally purchased an annual plan ($240) instead of monthly. Requested a refund on the same day with 0 credits used. Support closed my tickets (#103328335, #103329002) within hours citing policy, with no escalation offered. No response to follow-up. Warning for non-English speakers: Their pricing page displays a very attractive low price, but one careless click and you are charged for the full year. The annual billing is not clearly highlighted at checkout — making it very easy to misread, especially if English is not your first language. A same-day refund request with zero usage should be a basic standard of customer service. Currently escalating to senior management and card provider."
