O2 DSL contract cancellation

Hello People,

I have subscribe O2 DSL Connection on 27.08.2017, later in Feb 2018 i moved to WG Wohngemeinschaft. In new place already Vodafone DSL is available. So i would like to cancel my O2 contract.

Now question is, can i cancell my O2 contract at the end of 1st year completion or should i pay fully 2 year contract Money to cancel it.

Or, is there possibility to get Transfer my O2 Connection to WG where already vodafone present. (2 Connection at same house is possible?)

I kindly request the reply/answers for above questions.

Thanks in Advance,

Nagaraj
