User complaint, can't cancel subscription?

Hello seaart ai team, I am a user, I have experience registering as a user and entering a visa card on seaart ai at the present time I am not suitable for this platform, and I have tried to cancel the registration. But why can't I cancel the registration, is it due to a system error? Or is there a problem that the seaart ai team still does not let users make their own decisions, but will make users dependent on the seaart ai system?
