cancellation

Hello, i want to cancel everything i am having with O2. Reason for that is because i apply for family package with 4 sim card(two for parents L, and two for kids S)in february 2022 and my wife's sim isn't active yet. Next internet for home.  Firstly I singed contract for cable internet and after they never connect me i visited their office and they told me that i should have new DSL contract because cable is not possible on my address. Tehnician showed up and there was issue with connection phone wire. I installed new one but they never come back. I visited their office again and than they told me that i can now hav Cable internet so i signed new contract.  And still after more than 4 months i do not have home internet and active 4th sim. So i want to cancel everything
