Flipkart — Grocery Fraud

Grocery App in the name of kilos in the subsystem of Flipkart app, there is a seller named as Suricybcombazaar who displays higher mrp and then delivers wrong products to the customers, as there is no return policy on Flipkart hence using this policy as the shield both Flipkart and This Seller Suricybcombazaar are fooling people and looting customers. Recently I purchased Navratan Oil 300 mL which mrp displayed by the seller was 320 but they delivered the product worth the mrp of 230 and now they are refusing to take it back. They charged 234 for the same .
