VR headset problem

Hello, please help me solve a problem. A few months ago, I bought a VR headset – the Oculus Meta Quest 3S. I successfully activated it and used it for a significant amount of time. However, one day, I was hacked across many messengers, including Meta Horizon. At first, I didn't understand what happened. I went into the game store, but there were some technical issues. After that, since no other method resolved the issue, I decided to perform a factory reset. Following the reset, I deleted my Meta Horizon account. I tried to go through the registration process again, but I was no longer able to register. I tried everything, but nothing worked. After that, I turned to an AI for help. The AI told me that, most likely due to the hack, something happened and I was banned on Meta's servers, including my headset being blocked. But since I deleted my account, there is nothing more I can do. The AI advised me to contact support, but a new problem arose: since I ordered it from a marketplace, I don't have a physical receipt for the product. Please advise me on what to do in this situation.
