Actually, the software is pretty amazing. If you're freelancing as a graphic designer, I'm not sure how one would get by without Photoshop, Illustrator and InDesign.
The best pricing is, of course, the academic pricing. If you're enrolled in a community college course, that's usually the easiest way to get that pricing. Actually, Adobe extended Creative Cloud at no cost until the end of May for students currently enrolled in a class.
I'd reach out to Adobe again and tell the agent that due to COVID-19 you cannot continue your subscription at this time. Also, you can file a dispute with your credit card.
Next time you sign up for something with a trial period, keep a close eye on the end date of the trial if you think you don't want to continue.
Oh, also, your subscription is a business expense that you should be able to deduct from your taxes (check with your accountant).
