I am another customer.
I have perhaps found something for you: the webform that you have to fill out, to end your insurance. See also the attachment. If you wish, I could translate the form for you in Italian. You donot need the digid, only your customernumber and you have to tell the enddate of the insurance. Check in any case if you receive a confirmation of receivement-email after you filled in the form.
Thanks for your answer Feina. You can stopp your insurance through the link that Feina gave you.
With this link you don't have to log in with your Digid. Fill in the form the date that you left the Netherlands and your adress (abroad) where you are living at this moment.
Within 2 weeks you will receive a written confirmation from us.
I wish you a pleasant stay abroad. If you have any further questions from us do not hesitate to ask them.
