Flipkart — Bluffing customer through False advertising

On Jun 20 2021, I've received a text message from flipkart on TV's under 14000 with a link. When I click on it, I was redirected to flipkart with the list of products & I noticed that the Mi 4a horizon edition of 32inch for 13882 and when I click on that product the price was redirected to 15999. I call the customer support of flipkart thrice and they just simply deny it by stating technical glitch initially and later informed that the seller might changed. I been trying to place the order from 30 after I received the message there wasn't any info provided on that page stating that the price has been modified due to seller change. I do have screenshots with proof of pricing. I would like file a complaint against Flipkart for false advertising and would like to purchase the product for the price initial promotion price with extra benifits displayed with the product
