@Marta Cristovao Welcome to our forum. 

I would like to check what I can do for you. Could you fill in your forumprofile with your zip code, customer number and the last 3 digits of your bank account. 

Then I will check if I can send you the invoice! :)

Hi @Rutger_ , thank for your reply.

I have updated the forum profile with the requested information.

To make it clear: I need the invoice of December 2019, which should cover the period from December 11 till January 10.

Thank you.

@Marta Cristovao Thank you for filling in your profile I send the invoice you were asking for by mail!

Thank you very much @Rutger_ .

I've received the invoice in good order, it's exactly what I needed.
