Cancelling the contract earlier as O2 is unable to provide a working DSL connection

Hello,

I have an o2 DSL connection in my previous apartment and everything was working fine until i moved into a new apartment on 31.05.2019.

It's been more than 45 days now and i still have no working internet at home. I created many useless tickets but they were simply closed without the problem being solved.
I had an appointment with 4 technicians, out of which 3 showed up and 1 didn't even visit me while i was waiting for him from 14-20. And after all these, none of them were able to successfully get the internet running.

One of them even blamed the o2 home box router. Earlier I was using my own router and now I even ordered o2 homebox hoping that, it would solve my problem.
I am tired of waiting and hoping for this problem to be solved and hence I would like to terminate my contract earlier than the given date.

I called the cancelation team and when i asked them to terminate my contract earlier, they said they need a confirmation from the technical team stating that the fault is from o2 for not providing a promised service. And when I called the technical support team and asked them to forward a request to the cancelation team, they said that they can only create tickets to solve the problem and have no access to communicate with the cancelation team. It's a dead end here and it's not fair to charge me without proving any kind of service.

I request you to kindly cancel my contract effective immediately and also refund the money charged for the last 2 months.
