Air India — Have been trying to reach to reschedule tickets due to covid

Hi . I was scheduled for travel on 12th January and ended up testing positive on 9th January . I have tried contacting Air India multiple times including the City office and they refuse to answer calls and keep re routing the number. I need to fly back as soon as I recover and I wanted my tickets rescheduled as per policy on their websites but even clarity of the process is not available. As a covid positive patient Am I Suppossed to call the airlines 500 times a day just to have a certain matter taken care of ?
