Cleartrip — substandard service and ineffectiveness

I wanted to reschedule the flight for my elderly parents due to the coronavirus pandemic. I have been contacting them for days and have been put on hold for hours. But no response. No communication. Nothing.
I have also tried their various e-mail addresses. Their social media platforms do not seem to be functioning. Understandable that a situation like this was not predicted by anyone. But, cleartrip being in this domain is mandated to provide at least this basic service to its customers, or some alternate.
