I have been charged for trial subscriptions that I canceled according to the policy

Unfortunately I have been charged for trial subscriptions that I canceled according to the policy. In fact just the other day I was charged for two apps that said the app prices is 3.99 for example for 3 days. If you don’t cancel before the time period then you will be charged a one year subscription. Immediately both apps that were AI did not work at all. I canceled the subscription. However, both apps unilaterally made an offer but unilaterally put me on a premium subscription that I did not want. Both charged me 29.99 to my card with Apple. Unfortunately I have found that iTunes or what used to help for charges like these would be addressed but this is almost fraudulent on the 3rd party vendors part. I’m not contacting Apple anymore. Time for someone in upper management to help. I have a few connections. Be careful!
