Hello,
Normally you should not be getting notifications to renew your subscription if you’re on autopay, did you check where these messages are coming from and if the email address is legitimate? This is a common scam tactic where you’re sent a fake email about a subscription you didn’t pay even though you already did, to try and get your bank details.
Since you only provided your receipt there’s not much else the chatter can do, no extra subscription will be added on top of your existing one.
If you wish to double check you can view your order history and subscriptions through this link.

Hope this helps,
