Order no: OD****************** Item name: Flipkart SmartBuy Back Cover for Asus Zenfone Max Pro M*, Color: Black I ordered this particular item with my Asus Zenfone Max Pro M* on **/**/**, Friday(*:** P.M) from this particular seller called SuperComNet using online shopping platform '''Flipkart''. The item reached Noida (my nearest Flipkart hub-Phase*Noida Hub ) on *th November at *:** am. Subsequently, the item was out for delivery on *th November, **** at *:** A.M. But, since that particular time, the order was out for delivery till now (*th November, *:** PM) I have not received my item/product. I also received a message from the courier partner of Flipkart called ''Ekart'' on (*th Nov, **** at *:** A.M), one at the morning stating that the product is out for delivery and will be delivered to you before * P.M. I was also sent a particular number (***********) in the message incase I want to contact the Wishmaster of the courier service. I have been continuously trying to call at the number, but no one is picking up the call. And in the evening of (*th November,**** at * P.M), I received another message that the product could not be delivered today and it will be delivered tomorrow on *th November, but till now(*:** pm -*th Nov,****), I have not received my product. I also contacted Flipkart customer care multiple times through emails, phone calls and chats, but they are not providing me any solution. All they say is that, ''Our concerned team is working on your issue and the product will be delivered to you soon''. Also I need to mention here that the product’s delivery date has passed by on *th November, **** and today is *th November, ****. As it is a prepaid order, they are not paying any attention to it. So, through this forum, I request the concerned authorities to provide me resolution for this issue. Thanks.
