R. S. Yadav Travels — no refund received for cancellation by bus operator

I have booked ticket for 15april 2020.
Bus has cancelled due to lockdown.
But i have not received my refund amount of inr 2500.
And there is no way to contact them. Every given number is switched off. Even on their app.. My cancellation amount is showing inr 1300 while i haven't cancel my ticket it was cancelled by bus operator itself.

I have no idea whether i will receive my actual amount of refund.
