That’s how it should work, but many services have been increasing pricing with email warnings for the last decade.

My friend has PS+ and it has multiplied in price for 3-month intervals without him ever confirming the new price. He’s had it for a decade without touching it and genuinely wouldn’t know he’s being charged so much more than he agreed to if I didn’t tell him.

This is in Australia which normally has better protections for consumers, but it might actually be the case that it doesn’t in this case. It’s happened to me with every subscription I’ve ever had they send a n email and then start charging an amount I never agreed to.

The only exception was AEW+ via Fite.tv which was in USD, that was the only time I ever lost my sub when the price changed, which given it went up +40% I was glad they handled it respectfully.
