Complaint, action required immediatly

I've cancelled my subscriotion with prime video last month due to 3 debits that they took from my credit card in one month. I had to fight with my bank in otder to get it reversed, and prime video only wanted to refund 1. Bunch of **********. Now, after my subscription is cancelled for past month and my card details being removed from my subscription, they again deducted from my account. Now again i need to fight for my money. I cancelled due to financial difficulty, and cutting extras. I want my money paid back ASAP, and a written proof that they are not going to deduct again from my account.
