Tady je odpoved, kterou jsem po delsim presvedcovani vyrazil z chat asistenta:

I apologize for the confusion earlier. When you downgrade from the Premium plan to the Standard plan after one month, you'll pay for the current month plus a break fee equal to two months' subscription. You can continue using the service until the end of the current billing cycle. This is applicable for downgrading within 10 months of the subscription start date.
