Charged monthly since May for a plan I can't find or access

I signed up for an Adobe free trial in Thailand (either Creative Cloud Pro or Illustrator specifically, I'm not certain which) intending to use it for just a few days. I forgot to cancel in time and was charged 3,889.45 THB in May.

I cancelled shortly after that charge. However, I've continued to be charged 525.37 THB monthly since May under the merchant name "ADOBE*ILLUSTRATOR," including again in July. When I sign into my Adobe account, I only see one invoice (the original 3,889.45 THB charge), no record of this second charge or any active plan tied to it. When I try to open Illustrator, I'm redirected to a "choose your plan" screen, confirming I have no active access.

I've tried Adobe's AI chat support to try to reach a staff member, but it told me I need an active plan to proceed, which I don't have, so it can't help me with anything. I have no other Adobe accounts or emails.

Has anyone dealt with this before? I'd like this charge identified, cancelled, and refunded, since I have no visibility into or access to whatever it's for.
