Cancel My Shortswave Subscription ASAP And Get Me A Refund

I have been repeatedly charged for a Shortswave subscription that I have been trying to cancel for weeks, and I can neither stop the payments nor find any proper support from the company. I originally started the subscription through the Shortswave app on my iPhone, which I downloaded from the Apple App Store and signed up for directly inside the app. I only intended to use the product for one week, but I am now being billed on a weekly basis. These Shortswave charges appear as recurring payments on my Visa card, yet the subscription does not appear anywhere in my Apple ID subscriptions list, so I cannot cancel it from there. I have been charged weekly since around 31 May and the payments are still ongoing. As soon as I realized this, I tried to cancel and sent my first email to Shortswave support on 5 June to [email protected]. Since then, I have contacted this address multiple times, clearly requesting cancellation of my subscription and asking for help, but I have received no reply at all. I believe the account may be linked to the email address “gkle***@gmail.com”, but the app did not clearly ask for or show my email during sign‑up, which makes it even harder to manage or cancel the subscription. Because the subscription is not visible in my Apple ID subscriptions and Shortswave is ignoring my emails, I am stuck in a situation where payments keep being taken from my card without my consent. I request the immediate cancellation of this Shortswave subscription and a full refund of all weekly payments that have been charged since 31 May. I also expect a clear confirmation that my account has been closed and that no further charges will be made.
