How early should we inform to switch the tariff from Red internet and phone 200 Mbps to 50Mbps

[Channa]

I purchased the tariff "Red Internet & Phone 200 Cable" on 09.11.2019. After 1 year I would like to switch the tariff to 50Mbps. May I know the latest date to inform about the switching?

Hi Channa,

correct, he is now the contract holder.

Unfortunately, your answer here in the thread did not reach us in the processing tool and was therefore lost. Here a short message would have been necessary if you do not receive an answer within a short time. Then we could have corrected this promptly. Unfortunately, a retroactive contract change is not possible.

Best regards

Lars
