Cleartrip — Flight Ticket booking and refund

Respected sir/madam,
I had done the flight ticket booking on Sunday morning 19th of July 2020, I got the e-ticket ( which did not mention if it was confirmed or not) .After a few minutes I got a msg and an email saying that the payment is still under process, after another 1-2 minutes I got a msg and an email saying that the payment wasn't successful, the payment failed so if the money has been deducted from my account then I would be getting the money back in 3 to12 working days . (I am attaching all the details )
I tried calling you and the airlines, Indigo, but no one was answering the phone, I tried calling the airport so that I could talk to any representative from the indigo airlines present there, but I just couldn't reach anyone. I have not yet received the refund.
As the web check-in also was not available to check if the ticket that you had emailed was a valid ticket or not . (Web check is only available 48hrs before the flight).
I had to get a confirmed ticket of Pune to Nagpur for the 21st July 2020 as I had to travel for my college admission . So I booked another ticket through another agent .
I checked in by web check-in later that is on Monday 20th July 2020 and I entered the PNR of the booking that you provided me in the e- ticket, and it was allowing me to select the seats and all, so that was an indication that the ticket booking was a valid one and hence I cancelled the booking but I got a message that only a part of the money that I paid that is only Rs 4860/- will be refunded, while I had paid Rs13040/-( I haven't received this refund, I checked with the bank as well)
Now I request you to make sure that I get the full amount refunded that is Rs13080/- as soon as possible because I am being charged for your mistake. You sent me an email that the payment was unsuccessful and the money would be refunded back . That is the reason we made another booking .
