Hello,  I need help for my Wifi contract.

My contract was going to end in May 2022, but last year in November 2021, I moved out within Germany.

I didn't know that if I change my address,my contract will be renewed for 2 years again... But anyway, when I changed my address and Telekom Techniker came to my new apartment, we couldn't find some kind of "switch" (source of Internet) in my apartment building, and so the wifi connection in my room can't be enabled. So I don't have internet at my new place now, and My contract has renewed and I have to pay every month again for 2 years... I would like to know whether I can cancel my wifi contract or not under my situation... Thank you.
