When you ordered a subscription what did the postal code check suggest for possibility of fiber? Is there a fiber connection in your house?
Hi @Angelina Davydova, welcome to our forum. If I understand correctly there are 2 different things happening? One with your mobile sunscription and one with the DSL/fiber connection? I don't know the exact situation, since there are no details on your profile. Can you tell us more about it and fill out your profile?
It's also possible to call us like Ernst-Jan mentioned. That is the quickest way to contact us.
