Flipkart — Complaint Regarding Bata Formal Shoes Ordered From Flipkart

This is one of the worst experience from Flipkart.. whole customer care department is useless they don't even note the customer grievances related to product.
I've ordered Bata Company Formal Shoes(Black), I received a used product without any MRP tag, No Brand Box, No warranty card.. they're fooling people by selling the wrong product and not making a single resolution through customer executives.. I've talked more than 10+ times to customer executives mentioned them all product issues.. still delivery agent is declining my return pickup.. it's really pathetic
