CandyJar Continued Charging Me After Subscription Cancellation

I am writing to raise a complaint about ongoing charges from CandyJar even though I cancelled my subscription about a month ago. Despite stopping the subscription, CandyJar has continued to bill me and I have now been charged approximately $100 after cancellation in the United States. The charges are being taken directly by CandyJar from my card ending in 6021. I have emailed CandyJar four times about this issue, attached screenshots, and clearly explained that I had already cancelled, but I have not received any response at all. The lack of communication and the continued unauthorized billing is unacceptable. I request that CandyJar immediately stops all further charges on my cancelled subscription, refunds the charges taken after I cancelled (around $100), and provides written confirmation that my subscription has been fully terminated and my card details removed from their billing system.
