Problem with plan cancellation and refund

Hello, I am very confused and upset about a situation that happened to me today, I received a notification today that over $400 has been debited from my card for a subscription renewal. Despite the fact that I had been trying to unsubscribe for several days, but each time the website would glitch and go back to the home page, making it physically impossible for me to unsubscribe. Another fact is that the renewal was settled in dollars for an absurd amount of over $400, which in my country is half of my salary, I am a student, so it is an additional inappropriate thing that such an amount was charged, because in my country for the package I would pay even 5 times less for a year. I am asking for help because after withdrawing the money, I literally have $6 left in my account. This is very upsetting and unfair that adobe took the money. The whole situation is from today, but despite the 14-day return of the product, after canceling the plan, which, strangely enough, I was able to cancel it only after an absurd refresh and deactivate the plan, it is impossible to contact Adobe support in any way, because the chat automatically ends the conversation all the time. I'm asking for help because I'm thinking about getting a chargeback from my bank.
