Internet has been out all day.  I don't know who to call to get it fixed or report the outage as I only speak English.

Hi,

does the issue still persist? First thing to try before contacting the support is always to restart your router by unplugging the power cable, waiting for 20 seconds or so and then letting it restart by putting the power cord back in. If that does not help, call the English language support hotline mentioned by @Christian Rosinsky .

Best wishes,
Thomas

Hello @JessicaBinsfeld 

Please apologize the late response. We just tried to reach you under the call back number you noted in your profile details, but without success, it seems to be a wrong number. Can you please check the call back number and correct it? And the most important thing: Do you still need help or is everything fixed?

Kind regards Nadine H.
