Flipkart cancelled order and denied compensation

So recently in BBD sale I ordered a PS5 game. I had bought a spefic game pass that gives addiotonal discount. After order was placed a month later Seller Retailnet cancelled my order and when i told whole story to FK escalation agent he gave a resolution of supercoins as part of compensation for the price diff in next 24 hours, I took a ticket number as well ..but after. Days there was no update then 3rd day a new agent gave me a new ticket number telling me that earlier there was no ticket raised. After checking here and asking few guys i got to know that I can write a grievance letter .where I meantioned all the issues.. then got a phone call stating that max i will receive a coupon code of 150₹ and the agent denied whole compensation thing that was discussed earlier. I told her that you guys have a recording and all to which she simply said there are no records.. even after kindly sharing my problem she repeated same thing and cut the call. I replied back to the grievance email of the same stating whole thing plus 150 ₹ is nothing to 1.4k loss. When i mentioned legal actions all she could she was thats you personal choice in an very offensive manner. I had sympathy for call support people as they had to listen to people's complaints but now I'm dine Plz advice..
