I had ordered a smartphone from flipkart and ekart was supposed to ship me to home. But when i received the out for delivery update i tried to call the phone number provide by ekartl sms service but the delivery person never did answered. Its been three days since the promised date of my order no fmpc[protected] phone no. Of delivery boy [protected] is over.
And while i called flipkart customer service helpline they asked me to wait till next two days, again they extended their deadline and pushing further
I have been stressed out and been through huge problem due to delayed delivery.
I expect ekart logistics to be banned.
I am asking for a quick action s on flipkart, ekart logistics and want my product delivered soon.
