LinkedIn Restricted My Account Despite Premium Subscription

I have a LinkedIn Premium subscription, but my account has been restricted for about three days. Although I have completed all identity verification steps correctly, the application does not open after verification. When I try to log in again, it repeatedly asks for verification and I am stuck in this loop on both desktop and mobile. When I try to submit an appeal form through LinkedIn’s own Help page, I receive the error message “We’re sorry. There was an error creating your Case. Please try again.” and the system does not allow me to submit the request. Since I cannot find any other communication channel or support line, I am unable to reach LinkedIn support directly about this issue. Because my account is restricted, I cannot benefit from the Premium service for which I have paid, despite my subscription being active on the account registered with the e‑mail address agi.ulu.com***@gmail.com. I request that my paid Premium subscription be cancelled, my account and all my data be permanently deleted, and the amount charged be refunded to me, taking into account the entire period during which my account has remained restricted and unusable.
