Firstcry.com — Complaint against extra charges charged

I bought a Babyhug stroller and Phillips Avent on 27th Aug 2022 from Inkpebble Stores LLP which is an authorised store of FirstCry. I found out that there is huge difference of price between online website of FirstCry and the products bought from showroom.
This is clearly fraudulent and charging extra from customers and FirstCry don't have any control of the price on offline stores. When I raised a complaint with FirstCry helpdesk they simply said these are 2 separate entities and didn't even bothered to look into the issue.
Online price of stroller Rs 3716.90
And for the same stroller we paid at store Rs 5575.35.
Online price of Phillips avent Rs 4410.09
And for the same stroller we paid at store Rs 4845.15
