PAN Deactivated - NRI

Hello,

Recently, my PAN was deactivated. I contacted the eFilling Helpdesk and they told me to contact jurisdiction AO. I am living outside India and in this tough covid times I cannot travel to India. So, it is difficult for me to find out who my jurisdiction AO is and how to contact him. So, I request some guidance from forum members to guide me in handling this situation.

Thanks
