Flipkart — Received wrong item and flipkart denying it

Hi Team,

I have ordered Panasonic AC from flipkart, but the item which was shown on website is different than what is delivered. also the item was tampered at the time of delivery. I have raised the complaint to flipkart customer care but no one is listening. also regarding the installation fees, first flipkart customer care told me its already included in the order amount. then told me its not included and I need to pay 1599rs but on flipkart website its shown 1416rs. Flipkart not ready to accept the complaint. I have evidences of everything and can provide if needed. the item was tampered but flipkart denying everything saying its open box delivery but no otp was shared at the time of delivery.

flipakart denying everything and not ready to accept the evidences. they are denying it without even seeing thr delivered item
