AIT3 Question for the team

Good day guys! I ask for a team response in connection with my problem. I was selected to participate in AIT3 and successfully participated. When the end of the testnet was announced, I decided to continue testing until Friday, but alas, on Thursday I fell ill and did not leave the active validator set. Yesterday I tried to leave the active validator set, but nothing happened. Please tell me how to complete AIT3 correctly. And how critical is my mistake? Can I count on the rewards for AIT3 or am I hopelessly missing out? With great respect for you.
