Does a month to month plan mean I have to cancel the plan every single month?

Hi,

I bought adobe premiere pro for a month back on 21st June and cancelled on the 15th July receiving an email confirming cancellation. However, recently adobe premiere pro re-appeared in my products list randomly and I had to re-cancel. I also received tons of emails urging me to update my payment details so I could pay for another month of use, even though I had cancelled and stopped using the application ages ago on the 15th of July as mentioned above. Will APP keep re-appearing in my product list each month and will they stop emailing me to pay for things I cancelled months ago? It's really frustrating as it doesn't state this in their subscription terms Legal subscription terms | Adobe .

Thanks.
