Flipkart India - Different product received in replacement

Flipkart sent me a wrong product in replacement (Acer Aspire A***-** on box MRP just **,*** and given below S/N:- NXGVWSI*******F*AE**** ).
I received replacement product receipt via email which is mentioned the same serial number on the receipt. You can also check on Acer's website given below
https://www.acer.com/ac/en/US/content/support
It's Acer Aspire A***-** Not Acer predator Helios *** and seller make receipt with the name of Acer predator Helios *** while this serial Number of Acer Aspire A***-**.
It's clear that Flipkart sent the wrong product and make receipt by wrong product Name.
This S/N:- "NXGVWSI*******F*AE****" Not for Acer predator Helios Model. I ordered Acer predator Helios *** i* and paid **,*** based on no-cost EMI. How can a seller make the wrong receipt with the wrong product name?
Flipkart support team sent a mail for consent for lodging FIR. Even I replied for same and I gave them consent "Yes proceed to please". Flipkart gave me * days and told me that they will contact me but they didn't call me and they cancelled my return request on * June. When I see that then again I contact Flipkart customer call and they again file return request and same day evening they cancelled my return request again and deactivate my Flipkart account. It is clear that Flipkart sent wrong product I have all proof and Flipkart not accepting it and not taking back wrong product sent by them.
I have already shared all necessary proof such wrong product images serial number mentioned and receipt via Email (cs@flipkart.com). Utterly disappointed by Flipkart support people who are not ready to help and just dodging queries and Not talking properly.
