Flipkart — Not providing buyback guarantee as per policy

In last year october 10, 2021, i have buyed vivo x70 pro with exchange my old mobile. I have paid 32727 rupees and i add one buyback policy with my order. As per the buyback policy if i exchange my mobile within 1 year with same brand i will get 32900 rupees discount and other brand i will get 16450 rupees and this offer will valid from 21st june to 20th october 2022. So as per policy i try to exchange my mobile with latest one on same brand. But i found that they are only offering 16450 rupees instead of 32900 rupees. I have attached some screenshots that they are not providing offer as per policy. Please take action regarding this so that i can avail my offer as per policy.
