I want my ordered product at that same offer price . How can they cancel it without my permission? I also contacted flipkart and they said that they can do nothing in this case your seller has cancelled it and as compensation we are giving you Rs *** gift card . I want to file complaint against flipkart for not completing my order (after getting paid ) and for mental harassing me on phone through their customer support by wasting my time and also not provided any help . I want that product at that same price. And one thing i also want to mention that i have not cancelled my order , flipkart has cancelled it.
