Cleartrip — not getting refund

We booked our 3 air tickets from jaisalmer to ahmedabad on 26th october 2019 at 12.40 am & cancelled on 27th october 2019 at 11.30 pm but still we have not refund our amount. Our trip id is [protected]
We need our refund amount asap as it has passed one month. As per your mail refund amount is 6812/- after deduction of all charges. After this i received email that refund amount is 0. How it's possible as i cancelled my tickets before 12 hours and as per rules i get minimum 50%
