Perhaps Google Nest Support needs to update their documentation..
Their "Cancel your Google Store subscription" page (https://support.google.com/store/answer/11264766) says the following:
1. Open the Google Store website.
2. Sign in to your account.
3.On the Subscriptions page, choose the subscription you’d like to cancel.
4. Under “Payment”, click Cancel subscription.
5. To complete cancellation and find an estimate of what you’ll be charged, follow the cancellation steps.
However, if I follow these instructions on our now Nest Aware subscription, there is no "Cancel subscription" option under "Payment".
However, I discovered by accident that if I clicked on the vertical ellipsis (the three dots), I then see this popup window (shown below with personal info blanked out), with "Change your plan" and "Cancel subscription" options:
P.S. When you had your "Chat" support session, were you talking to "Nest Aware Premier Care"? See the "Contact us" link on the page below, which promises you can "Get 24/7 access to Nest Aware Experts on the Nest Customer Care team. They’re available to answer questions, help you access features, and manage your subscription."
