I suspect my Vermieter terminated the internet contract without letting me know beforehand.
For the context, I'm using cable Internet by Vodafone. My Vermieter was the one who made the contract since I don't know how long, perhaps longer than 5 years. Since last thursday, the internet has suddenly dropped to almost 0 Mbps. I checked in 'Vodafone Störung-Finder' and it said 'Keine Störung an dieser Adresse ist uns bekannt'. I called Vodafone, but they asked for the Kundennummer, which I don't have. I've been trying to contact my Vermieter since the problem started, but so far he hasn't contacted me back. I sent him a Whatsapp message on last friday. I saw that he went online so many times after that. Now the questions: 1. Is there a way to check with Vodafone whether there's still an active contract going on at my address? 2. Can I just walk in to some Vodafone shop and open a new contract without doing 1.?
