Trying to cancel sky

I joined back in July 2024 and the price has doubled since then. I tried to cancel sky TV as we barely use it but keep the internet, however as I'm still in contract they said i can't. I tried to reduce the bill after being told I couldn't cancel but the guy on the phone ended up adding another broadband package (which was more expensive than our current one). When I told him we didn't need that, he cancelled the original cheaper one, left the more expensive package on there then charged me £30 for admin fee?? Also told me if I wanted to remove packages then I'd have to recontract for another 2 years. What a scam. How do I actually get around this and cancel it for good? I don't care if I have to pay a cancellation fee. I've read online if I tell them I'm moving abroad it's easier? I have a phone contract with them as well, which I don't want to cancel.

If I knew it would be this difficult to cancel and they would end up charging me double in less than a year, I would have never signed up. Any advice or help is much appreciated! Thanks
