I did read your first post and your reply where in both you said you cannot use the subscription. Since you apparently cannot get a refund your alternative is to get the subscription working and for that you need to contact the developer.
"claude was blocked my account after 2 days of using," -- Why was it "blocked"? If you violated the developer's terms of use then it was your fault and I do not see that you have any recourse.
As for your refund, the developer cannot refund you. Apple can, but only according to their legal documents where the ones I read said they make refunds for unavailable or defective product. If you were "banned" by the claude developers then that's neither of those. Apple was right in telling you that to get access to your subscriptions then you need to contact the developer. Apple was not telling you to contact the developer about getting a refund from them, only in avoiding the refund issue altogether by getting your subscription working again.
So my understanding of it is:
-You purchased a subscription and a few days later were banned from using it. Why, you have not told us but we do not really need to know. Generally if you abuse the terms of service you are at the mercy of the terms of the contract to which you agreed when signing up.
-You wanted a refund and asked the developers who are not responsible for the financial end of things and they rightly sent you to Apple.
-You if not qualify for a refund from Apple so Apple said no. They also suggested you get the subscription working gain and for that you had to work with the developers.
-You think you are being given a runaround but in fact you are not. Each team is doing things as they should.
-Since you cannot get a refund I have been suggesting that if you can at least get the subscription working again then you won't come away from all this empty-handed. This is kind of what Apple was suggesting too. To get the subscription working again you need to work with the claude developers as they invited you to do in that message to you.
