Hi @TuJu 

On the main page of MijnKPN (website) you’ll find only the last 4 bills.
However, when you select “Producten” at the top of the page you’ll find all your products.
Select one and you’ll see the last 12 bills on the right. Click on “Bekijk alle facturen”.

If you use the MijnKPN app, you can download the last 20 invoices.

Hi @TuJu, welcome to our forum. I see Ruud has already helped you out. Did you find the invoice using this method?
