Transfer connection from previous tenant to my name

So how do I just change the bank details for now? Is that possible over the phone or here? I just want to make sure I don't lose internet connection.

Hi,

do you know the former tennant personally? Because we can't change the bank details without his permission and the contract details like his personal identification code. It is not enough to tell us the landline number.

If you have some details about the contract you may get in touch with our customer service. We can't do it right here. Sorry.

Kind regards, Manga

I know her personally, and can request her to provide you with the necessary details. This is just for a month so that I can then get a new connection myself.
