I want to cancel adobe stock

I everyone, I see this has been a problem for loads of people, but I'm now one of them. I want to cancel adobe stock but just cannot find the way to do it. It's obvious that it's designed this way to make people give up and forget about it, while that 34$ gets siphoned out of your account each month. But they are now having a payment difficulty with a card so I just remembered to pick up the fight again. Please help, this is absolutely ridiculous!
