Flipkart — flipkart and delhivery courier fraud

I had bought google pixel phone from flipkart on 1/10/19, through flipkart seller omnitechretail. The product was shipped on 3/10/19 via delhivery courier, with tracking id[protected]. It reached the nearest hub on 5/10/19. Since then delivery was not attempted even once. Both flipkart and delhivery courier are not responding, and flipkart is refusing to cancel the order. I suspect a fraud is going on. Please help me in getting my money back
