Hi, My DSL is not working since yesterday. I did everything as in this tutorial, but calling customer support was nearly impossible in German, I have the pre-ticket number generated from my android phone, how can I find my four-digit customer identification code is this part of my customer number??? Thanks in advanced for your help.

 

(Moved from FAQ to a new topic, o2 Michi)

@Dayta You assigned the four digit customer number (PKK) by  yourself when you signed the contract. (o2 Shop or o2 Online) Did you know the landline number from your contract?

Hi @Dayta,

I’ve moved your post from our FAQ into a new topic, just for your information.

Thanks @Joe Doe for your help.
