Help with refund for hidden Adobe Stock subscription

Unfortunately, I was somehow unaware I've been paying a 29.99 monthly fee for Adobe Stock for the past 10 months. I started a trial at some point and thought I had canceled. I recently went to gather a few stock images and realized this by the high number of images I had available to me through my account. Though I was able to use a few images, I have absolutely no need for the rest of them, or a continuing subscription. I am going to be rebilled for this subscription on tomorrow's date, and am now faced with having to choose and download 105 images in one sitting or lose what I have (accidentally) paid for.

I am looking for a refund for any part of my subscription over the last 10 months- as it is easy to see I have not been using it and have no need for the remaining images. I had no idea my subscription to Adobe Stock past the free trial had been ongoing apart from my CC subscription. It was in no way obvious.

I have already contacted support via chat and can provide a copy showing that he did not understand my issue. Have been seeking help via other forums where I have seen MANY others with the same problem, but am at a loss as to who else to contact, and so am posting here. Any help would be appreciated.

Thank you.
