Not possible to downgrade the contract

[Valeriy]

Good Morning,

I want to change my tariff from "Red Internet & Phone" 1000 to "Red Internet & Phone 250 Cable".
But I cannot see this tariff in the list of available options.
Could you help me, please?

Thank you

You can only downgrade your tariff after the minimum term has passed.

One exception: If you got the right to downgrade within a trial period of 6 months - but then your contract should tell you how you should get this downgrade done. As far as I know, this cannot be done at the self-service portal but has to be done through the hotline (in German language).
