Flipkart - Hp Laptop Non delivery

On **th JAn,**** I ordered a HP LAptop from Flipkart which was supposed to be delivered by **th JAn.On **th Jan,i received a text message that my order is out for delivery and delivery agent's contact details were in that message.I contacted delivery agent from Ekart(courier partner of flipkart) and he said i will deliver it by *pm.Later same day at *:**pm i received another text which says your product can not be delivered due to rejection of exchange product but the fact is no one ever came to deliver at my door neither i received any call from any one for the same except for the call i made.Later i called flipkart customer care and they assured that your product will be delivered on **th Jan as mentioned the delivery date on flipkart.But when i didnt receive my product on **th Jan also then i registered a complaint in flipkart and national consumer helpline soon after which i received call from escalationteam of flipkart assuring me to resolve my issue within ** hours or maximum by **th Jan.But next day i received a text message that my issue will be resolved by **th jan and today i received another message that my issue will be resolved by *st Feb.However on contrast i somehow got the address of Ekart office where currently my product is and i visited them this morning and the person over there told me that they will attempt to deliver it today or tomorrow.Now the matter of fact is my product is with Ekart and i confirmed same by visiting their office personally and still flipkart is sending me message that my issue will be resolved by *st Feb,**** and they are just delaying it again and again..I m not sure why? I request to please act on it and help me to get my product as its already * days past expected delivery date.
