I cancelled my CC subscription (see screenshot proof) and I'm STILL getting charged. Refund?

As the title states, I cancelled my CC subscription before the renewal date because I did not want to keep the subscription. A "real" person helped me do it (before convincing me to stay, of course), but I did not want to as my computer unexpectedly broke and I cannot use Adobe products on the replacment I'm borrowing for now. She eventually gave it and let me cancel. See screenshot for proof. This conversation took place the first week of January so I've STILL been getting charged for THREE months for a service I am not using and was told was cancelled. How can I get these three months reimbursed? And get the CC cancelled without paying a fee? I'm pretty livid.
