Paypal - How to stop recurring

I am getting regular notices from PayPal about recurring contributions.
How can I stop these from recurring?

Normally, you’d contact the person receiving the payment. If you can’t do that, you can cancel the payment within PayPal.

However, note that doing so only cancels the payment. It doesn’t cancel whatever service you’re paying for. This means you still owe that company for whatever service they’re providing, and may still have to communicate with them to actually cancel the service or to settle up your final bill by another means.
