COMPLAINT ABOUT BILLING

After reading messages from others, I see I am not alone in my complaint against Adobe's Customer Service. Back in early 2019, my high school son was required to purchase the Adobe Photography program for one entire semester. Although I balked at having to pay the monthly subscription of $9.99, I did in order to have my son meet his course requirements. Unfortunately, because I entered a credit card number on an account we hardly use, I didn't quite notice the $9.99 charges and I also figured my son could probably make use of the Adobe Photography product for the remainder of the year – and going into his Senior year. Well, he hasn't used the product since completing his photography course in April of 2019, and he hasn't opened ANY emails for Adobe since. However, when I checked my last credit card statement and noticed a charge for $19.99 for the Creative Cloud product on 2/27/2020, I confirmed with my son that he didn't order that. Yet, my credit card was charged the $19.99 without any verification from him or me, and without ANY authorization. My son immediately contacted Customer Service and so a meaningless conversation ensued. (See attached if you want to see what I mean!) What can I do to obtain a refund for a product that I  didn’t order NOR authorize at any point? My son also didn’t order any product or accept any free trial or additional service of any kind. Who can I contact without speaking to someone who isn’t understanding my typed words of ANY KIND? I simply can't afford nor need the charged product!!!
