Flipkart — Delivered wrong product

I have ordered realme buds wireless 2 headphones from Flipkart and cost of the headphones is 2300rs. After 2 days I received order from Flipkart and in my order package the box was proper but headphone was not proper. I received different model of the same brand. I received realme buds wireless 2 neo which is old model and there price is almost 1400 only right now on Flipkart. Then I requested for replacement but still I haven't received any proper updates from Flipkart. I tried so many times for replacement of the product but they always mailed me like your request is cancelled by 3rd party. And now my replacement days also expired. I need help to get my actual product or refund from Flipkart.
Thank you.
