Trujet Airlines — Payment wasted

I have booked a TruJet ticket from Bidar to Bengaluru on 23rd January 2021 for the 29th January 2021 in the name of Veeraditya Kushnoor with Premium Seat and Bundled meal included. amounting to ₹1000/-.
However, on the flight from Bidar to Bengaluru, he was made to make a payment of ₹ 300/-. This is highly irregular and amounts to cheating passengers. Please make note of this and try to resolve this issue with an apology if not refund of the amount.
