FlickReels, I Request Canceling Subscription On Already Deleted Account

I had an active paid subscription with FlickReels linked to an account that has since been deleted. Despite the account being deleted, the subscription is still being charged to my credit card at 19.99 per week. I have contacted FlickReels customer service on July 12, 13, 14 and 15 to request that this subscription be canceled, but I have not received any reply to any of my messages. The charges are continuing even though I no longer have access to the account. I request that FlickReels immediately cancel this ongoing subscription associated with my deleted account and stop all future weekly charges to my card. I also expect a clear written confirmation that the subscription has been terminated so that I do not face any further unauthorized payments.
