Submitting a new contact person
The name and email address of the contact person are part of your login details, and you can edit them yourself. Log in, go to Login → My data and enter the details of the new contact person there.
You can also email the details to the helpdesk at helpdesk@laposta.nl.
Are there other changes to your administration? Then please also submit a modified billing address or a changed company or organisation name. Is a colleague taking over the entire account? Read how you can transfer your account to a successor.
