You have to call the Hotline.

Dear @Lucho ,

welcome to our community.

You need to contact our hotline with this problem, as @schluej  already correctly wrote, so that a fault ticket can be created for you there. This is necessary and can only be created via the hotline, unfortunately this is not possible here in the community.

You can install our  o2 my Service App in advance and use it to check your connection. Something may already be detected and recorded in a ticket that the technical team can then access.

Kind regards,

Andrea
