Freezing a card doesn’t mean the debt is erased. They can still take you to collections.
For you to put together this sort of argument with a straight face, you need to have little to no understanding of how the internet in general, services and web apps work. Good luck arguing your case with a judge.
In this situation if it were to actually go to court I’d expect the actual bill to get significantly reduced at the very least. But because it’s a completely bullshit charge based on bandwidth usage (which costs them nothing) it won’t go anywhere near that and will just get written off anyway.
