Cleartrip — cleartrip customer support not responding, we need the full refund

Dear sir/madam,

I am writing to you in connection with the flight : goair flight g8-384 from mumbai (Bom) to goa (Goi) on[protected] at 22:10 hrs is cancelled.
I had booked 5 tickets and require full refund for the same since it has clearly been mentioned in airline policies full refund can be claimed. Also i would like to mention that customer support is not responding to my calls.
I have been trying to contact cleartrip past 10 days. Even their app doesnt work properly so cant do anything online like cancellation as it doesnt display refund amount and sometimes displays error message.
Please ensure full refund is done.

Please respond asap. Kindly find the error message attatchment which appears on cleartrip app.
Kindly do the needful at the earliest.
