Flipkart — Scam in name of big billion sale

I buy a product heavy duty electric angle grinder machine, that product was defective. This product was delivered on 9th oct, same day i created a return request but the pickup partner of flipkart not came. After 4 days that pickup auto canceled saying that customer want to keep this product which is completely wrong, i again created a request it shows this will be picked up earlier, its been 1 week still they are not coming and customer support not responding to my mail or any message. Flipkart doing scam by the name of big billion sale, giving duplicate product or damage product, please help me on this. Everyday they are sending today pickup but night they are canceling and in next day they are updating customer cancel pickup. The wrong words they are saying.. Attaching the screenshot. Shame on kalyan (Ceo) who hired the 3rd class employee and indian govt by seeing this issues from several customer not taking any action against flipkart.
