If you bought a zistemo subscription, you shouldn’t pay it manually each month. The amount will be charged automatically from your card.

But if your card is about to expire, zistemo will send you an email notification about it at the beginning of the month when your card expires. Therefore, remember to update your card information on the zistemo subscription page.

Also, on the 10th of the month before the expiration month, you will see a notification on the top bar:

If you completely forgot about it, no worries! You can still use your account for full 9 days after the charging date. We know you’re busy, that’s why during this timeframe, zistemo will send you daily email reminders.

Also – on the top bar, you will see a notification regarding the failed attempt to complete your monthly subscription payment:

You will receive the same messages if something is wrong with your card (not enough money, etc.).

Therefore, you have 9 days to update the card details before having your zistemo account blocked.
