My DSL is not connected yet

Dear O2 Customer Servive

I recently ordered a DSL connection 

The connection was going to be set up in January the 17th 

Technician came by to fix the line

Also O2 sent an email to me that says connection is available to use

But when I enter my Benutzername: 081*********@s93.bbi-o2.de Passwort: **********

Nothing happens.

I can't reach customer service

When I call 08005251378 they say we don't support English

Technically I can't do anything

I don't know what to do.

Please help me 

Kind regards,

Mohammad
