Cleartrip — 2 tickets same pnr no refund

I booked a ticket from cbe to hyd trip id is[protected]Dec 05). Paid rs.5258. But i didn't received confirmation mail immediately from your side. So i booked another ticket cbe to hyd trip id is[protected]., paid 5258. Immediately i got the confirmation. After few minutes i receive the confirmation ticket for trip id[protected]. I dont want two tickets on the same day. So i cancelled the ticket of trip id[protected]. Cancellation also accepted and i received the refund rs. 748. December 05 morning i went the check in inside the airport, that time the staff from indigo said, my ticket already cancelled and names also not there in passenger list. And he said that your both tickets are having the same pnr number (Fg5msp). How the two tickets will get same pnr? Because of the mistake from cleartrip i lost my confident and respectness in airport. Its a very bad experience for me. Then i booked another ticket from indigo for my travel pnr is nmi1jn. Today i given a complaint to cleartrip and i received a call from cleartrip number [protected]. He didnt say any proper answers for my queries. (My mobile number is xxxxxxx885). So i kindly request you to return back my full paid amount for both the tickets i have booked. Because mistake is from yourside. Hope you will do favor for me and problem will get solved soon.
Thankyou.
