Srilankan Airlines — Refund not proper cancelled ticket 6VFPLB and 5TLH6I

Hi Team,

I have booked two tickets and canceled them. After receiving refund the amount was two low what I have got. Not sure why the difference is two high. Here the details of the tickets:

email id through which I booked the tickets : pdp.[protected]@gmail.com

1. Refund request Reference number: UL/RR/138243 (MAA - MEL), ticket #[protected]
I booked this ticket for 1, 29, 751 INR but received a refund of 81, 890.47 INR.

2. Reference number: UL/RR/138436 (HYD - MEL), ticket #[protected]
I booked this ticket for 60, 550 INR but I received a refund of 37, 250.82 INR.

Can you please check why the difference is two high? Before Cancelling the ticket I called the customer support and was told 4, 500 INR will be deducted for each ticket. Not sure why I got way too less amount back. Please expedite the process.

I have attached all my tickets and refund request emails.

Thanks
Pradeep
