Cleartrip — Credit shell not accessible for a cancelled flight

Address:	2006 embassy habitat
Website:	Cleartrip.com

I had booked a ticket on clear trip on may 30, to travel from Bangalore to Delhi on June 1. The airline was indigo. The airline cancelled due to covid the previous night and a credit shell was offered to me. Now when I go for booking a new ticket the credit she’ll option does not show Uk even when I bill out in my trip I’d or booking pnr.
I need Clear trip to fix this because when I try through indigo they say I booked through an agent (meaning cleartrip) and need to approach them, not indigo
