Please look at the invoice. What exactly were you charged for? It could just be the connection fees.

Hello @Alicia707,

please have a look into the whole invoice. On the first page you will find the period that the bill is created for, on the following page you will find for which days within this period any costs or base fees are billed :-)

Regards,

Lars

Whenever I try to see the invoice from the computer, it redirects me to the O2 page and tells me that there are technical problems so the invoice cannot be seen. On the other hand, he tells me I can look at the app on my mobile (I have it installed), but he never lets me in, he tells me that my password is wrong and when I tell him to change it, he doesn't send me any email. :( 

In order to be able to use "Mein o2" for an o2 DSL contract, the customer must register the contract for "Mein o2" by entering the landline phone number belonging to the contract. If the customer does not do this but tries to call up contract data with a prospective customer or community login, he will receive the above-mentioned error message because such accounts are not linked to a DSL contract and therefore no data is available that could be displayed. Before registering, you must log out of the interested party or community account.

All price components can also be found in the price list. 

Hi @Alicia707, 

did you try the suggestion of @blablup?

Please have a look also to these instructions: 

Did you already find out the reason for the unexpected high invoice?

Loving greetings,

Hello!I have seen the video and I have reached here, where they put me:“We would be happy to send you your personal customer identification number by post. Please note that this can only be sent to your stored contact address. For security reasons, the dispatch will only be triggered if this contact address has not been changed in the last few weeks. Please enter the landline number of your O2 DSL connection.” Then I put the “Festnetznummer/aschluss” which is a 12-digit number that begins with 0 and they say to me: “Thank you. If you have not changed your contact address in the last few weeks, we will send you your personal customer identification number immediately by post.” But it never reaches me… I have done this step many times and the email does not arrived and not a single mobile message either. I do not receive anything. :(

Sorry, I forgot to explain in my previous message that after they asked me for the “aschluss” (which I put right), the next step was to choose a user name, and a password (whatever I wanted) but they also asked me for the "persönliche Kundenkennzahl ", which I only know is a 4-digit number but in none of the documents that O2 sent me does it appear ...
So I had no choice but to put the option that the number would be sent to my email to be able to put it and go to the next step. That is the email I am waiting for, to be told by my "persönliche Kundenkennzahl".

Thank you.

You will find the 4-digit PKK (personal customer identification number) in one of the emails you received from Check24.

Hi @Alicia707 

are you in need of assistance concerning the PKK? Shall we send it by post?

Greetings
