Ibibo Group / Goibibo — Unable to book my flight on credit shell voucher

Booking I’d with goibibo : gofld69c[protected]. I have a valid credit shell and I am unable to book the flight via same. It says invalid shell when it’s still valid.

You are also not allowing to change customer list which is legally allowed. This is so frustrating.

Please allow me to use my hard earned money to book my flight.
