Unfortunately, AutoPay can be unreliable at times.
You can make a manual payment to resume service. Login My Account using browser with incognito mode, click on the button Pay and Resume Services Now
If no such button, use this link on the browser and load enough funds to renew (remember to add E911 fees if your province has that charge)
