Hi,
The o2 technicians came last Friday to set up DSL, they did so and left saying everything should work. Since I'm using my own router, I'm supposed to go to mein O2 and use the user name and password I received in the letter they sent me. However, the data have passed and the 'Tarif und Optionen' menu item (where I should type in the username and password) is not active, it's in grey and I cannot click it.
The WhatsApp chat help offered to put me in contact with a helpdesk person, but it didn't and I can't reach anyone over the phone. What should I do?
Best,
Edit o2_Lars: Expanded the title to show also the router you are using
