Where is the detail of the Verbindungen & Services increase?

To do this, open the *individual connection proof* in the customer portal

I got an increase in the bill for “Verbindungen & Services” but I can’t see the detail anywhere. I see there are videos and explanations, but I want to know the details of my specific case. How to get the itemised bill?

It says nothing is available. I was charged 39 euro extra

then no individual connection proof is ordered. Unfortunately, you can't find out where the costs come from.

@Bumer Is there any way to order individual connection proof 

No.

Good morning @JJong 
Welcome to our community, I am very pleased that you are contacting us here 🤗

Please don't be surprised - I have added your 2nd post here so that it remains clear for everyone.
Unfortunately, you have not consented to the storage of your itemized bill data, so no itemized bill has been created. You can set it up for the future, but not retroactively. 
Chargeable calls can be, for example, calls abroad / to a special number or calls outside the EU (if this were the case, you would also see it on the bill page 1)
Have you made calls abroad / to a special number?
Best regards, Kathi 🌞

@o2_Kathi I have not made any international calls or calls to any special number. Could you please turn on the itemized bill data?

Hey @JJong,

i hope it worked out. If you need further support, please contact us again in the community. :)
