Cancel All Subscription And Refund My Money

I am an iPhone user and my subscriptions are managed through the Apple App Store. Previously, I had already cancelled all of my subscriptions, so I was very surprised to see that on 2026/10/06 there was a money deduction on my Korean bank card for a payment related to uMobix. I did not receive any notice or prior information about this charge, and there have been no other uMobix charges before this date. Since I had already cancelled all subscriptions earlier, I consider this withdrawal to be unauthorized. I request that this payment taken on 2026/10/06 be fully refunded, that any possible uMobix subscription linked to my Apple account be completely cancelled, and that my uMobix account, if still active anywhere, be permanently deleted so that no further unauthorized charges can.
