I have worked for two months in one company during the COVID-19 pandemic using my personal laptop. Unfortunately, my laptop got damaged, and due to the lockdown, all shops were closed, making it impossible for me to repair it. Without my laptop, I was unable to continue my work. When I informed my team about the situation, they told me there was no need to log in anymore, so I stopped working. However, they are now considering me as an absconder and are refusing to provide me with a relieving letter. What can I do?
