Extranet account and access management

I have a problem, how do I contact customer support?

How do I get an account to access the extranet?

How do I update the email address associated with my account?

What do I do if I’ve changed phones and my One-Time Password (OTP) application isn’t set up?

How can I check the list of recipients of renewal notices?

What different rights can be assigned to a user?

How do you distribute different services to different user groups?

How can I group several services for the same customer in renewal notices/invoices?
