Jetpack billing

Hello, all.

I stopped using WordPress years ago and still am getting billed an annual fee for Jetpack. I’ve forgotten which email address I had used to set up the WordPress.com account so logging in and cancelling Jetpack is not an option. Is there a way to identify a WordPress account by the bank transaction? There’s a 10 alphanumeric string after “JETPACK” that I hope identifies the account. Thanks.
