To cancel a PC’s subscription, press
Delete subscription on its row below: nothing more is charged for it (a renewal of it already being charged is refunded).
Invoices, card and cancellation cancels every PC at once, at the end of its period, and refunds nothing.
Details · the 14 days and refunds
Within 14 days of subscribing that PC — for a subscription you bought and put on a PC with none, of buying it — deleting is a withdrawal: the time it paid for stops at once — the PC stops then unless it holds other time — and the unused part is refunded. After that, the month in progress runs to its end, and every whole month that subscription paid for in advance is refunded. A purchase itself can be withdrawn from within 14 days of buying, under “Recent purchases”.
