I cannot find my subscription which I want a refund
I have taken a camera app (b612) subscription and it has in app purchases for premium subscription and it had a free trail of 7 days for which I have signed up and the Apple id have asked me to set up a auto topup for the payment method. 7 days have been gone and the and the app charger itself a premium subscription for which I haven't given any permissions . As the trail ended it had automatically charged my money through auto pay . I don't want that premium subscription and want to apply for refund. And I have cancelled the premium subscription and it shows it has been expired and now there is no app that I have taken subscription and no option for refund. The premium of the has been taken off and the refund option is not been showing in refund section. Please help me to find a solution for my problem.
