Vistara Airlines — refund of amount of cancelled tickets pnr no. uu2myg

The ticket for delhi from portblair was booked having pnr no. Uu2myg fpr the passenger —
1. Kashu dua
2. Shragharika dua
But due to spelling mistake in name the ticket of passenger no.1 was canceiied by vistara air linnes on my request and fresh ticket was booked for same person with correct name akash dua with pnr no. Onznou. And minor mistake will be corrected in the passenger no.2 as told by customer care attendant. It has been told at portblair air port that the ticket of shrangharika has also been cancelled by irctc which was never requested for cancellation. Due to this we were very in trouble at portblair air porton 17/6/2018. The fresh ticket for shrangarika dua again purchased on very high rate vide pnr no. Vou8jp. I have not received full amount so far and excess amount which i have paid during purchase immediate ticket vide pnr no. Vou8jp. Therefore request to refund total amount in addition to excess amount paid by me during purchase immediate ticket.
