I received a renewal notice for my digital signature.

Customers who pay by credit card will receive 3 renewal notices via email in the month leading up to the expiry of a digital signature. If your subscription is not renewed before the expiry date, your digital signature will be revoked. Please note that if your employer has a billing account with Notarius and your work email is issued through your employer, then you may bill your employer directly. If your digital signature was revoked and you wish to reactivate it, you must first resume your subscription. Please see I used to have a digital signature. What is the process to get a new one?
