Unauthorized charge attempt after subscription cancellation

Dear Apple Support,

I am contacting you regarding an issue with a subscription that I have already cancelled.

• 
  
• App: Chem AI – Chemistry Solver
• 
  
• 
  
• Subscription cancelled: 18 June 2025 (see attached screenshot)
• 
  
• 
  
• Despite this, on 03 October 2025, Apple attempted to charge 1,470.26 MKD to my Debit Mastercard (see attached bank message). Luckily, the transaction was declined due to insufficient funds.
• 
  

This charge attempt should not have happened since my subscription was already cancelled months ago. Please make sure that:

1. 
   
2. This subscription is permanently cancelled.
3. No further attempts will be made to charge my card.
4. Any mistakenly applied charges are refunded.

Thank you for your assistance.
