Adobe tried stealing my money

I know I should be more on top of checking my bank account- that's on me. However, not the point I am just ranting.

Today I noticed there was a $29.99 charge on my bank account from 4/20, and I realized I've been getting this charge since January 2024. I was at a complete loss, since I know for a fact, I cancelled my personal Adobe account, I even have a screenshot of the cancellation. Keep in mind I have two accounts: one that my university provides (I've made no purchases on it, and never touched it so the account basically doesn't exist), and another personal account (I had to make a purchase there, $19.99 a month for a year).

I reached out to customer service about the $29.99 charge I've been getting since January, and they said I purchased something on my university account on January 13, 2023. I told them according to my Adobe billing history, there is 0 record that I purchased anything. They sent me to another person- and let me tell you: rudest dude possible. Despite showing my bank account Adobe charges that don't line up, and a screenshot of the 0 billing history on my university account, the person not only spelled my name wrong, but also told me I may be using the wrong email address, they couldn't give me a refund because of the 14 day rule, and offered free credit and free access to Adobe for the next 3 months. I told him I have no confirmation email on my school account that I even purchased something. They said they see the emails getting sent to me, and to check my emails "that I opened". I haven't deleted anything from my school email, and saw I haven't received anything about such a purchase. I told them that, but as a follow up, they only sent me an invoice from 4/20. After telling them I have no email history, I gave them the benefit of doubt and said "Please give me an invoice showing my purchases on my university account because I don't have access to them". (Again, my university Adobe account says I have 0 billing history). They told me to check my emails even though I told them I did not receive any emails about a purchase. Their follow up in a nutshell: we cannot give you the refund, verify your account here's a link to your university account. You probably can't see your billing history because you didn't verify your account. One, when I clicked the link to verify, it didn't even let me verify my account (proving my point earlier that I didn't touch the university account). Two, this dude is reluctant to send me an invoice in general. So I called them out and asked why they won't send me an invoice of this purchsse I supposedly made, and since they're so reluctant I'm going to assume they're stealing money from me and I will take it to court. After getting transferred to an executive supervisor, without any problem, they issued me a refund for the last 4 months and said that my account "wasn't cancelled properly". This back and forward exchange went on for almost an hour.
