Two weeks before your subscription expires - they auto-renew if you didn't disable that function. I didn't disable the goddamned function and - of course - they auto-renewed me for the Cadillac plan that's $160 a year. My perfectly fine cheapie plan was $60.
I'm in the process of trying to get a refund and I'm not enjoying it.
Lots of people recommending Mullvad which I have heard great things about, but worth noting it doesn't have port-forwarding. If you're doing any sizable amount of torrenting you may want to consider ProtonVPN which at least has partial port-forwarding support.
