Kicked off

Hi all, A team leader wrongly accused me of using AI; it was just an assumption on his part. I explained to him that I wasn't doing it, but that I do, however, translate from French to English, which is perhaps why he had this doubt. He wouldn't listen and escalated the case to support, who deactivated my account. I contacted them, and they told me the account was permanently blocked. What can I do? Because I have truly suffered an injustice. Can someone help me please ?
