Hello Telekom

I don't speak good German, so posting in English. People absolutely do not help in the chat box.

I made a contract for Internet- Magenta at home M Hybrid almost 2 years ago, and now I want to cancel it as the 2 years is coming close to an end. Since its an Internet DSL connection, I cannot find anywhere on the webpage any form to cancel it, neither I can add my contract there, as it always asks me for my phone number (mandatory) -however my connection has nothing to do with my phone. Please advise.
