Ekart Logistics — product delivery carelessness

Website:

www.ekartlogistics.com

I ordered a tshirt on flipkart and it was supposed to be delivered by 28/09/2017 i got message of package delivery and to be ready on delivery address which was my office address. I waited till 2 pm but delivery guy didn't come. I tried calling on number which was in message but it didn't got connected. Afterwards i got message saying your delivery cannot be completed and package will be delivered by tomorrow on 29/09/2017. On this day (Means today) same thing happened. I messaged ekart on their website too but didn't got any response. I need my package as early as possible. My order number is fmpc[protected]. That delivery guys number is a terrible joke. Ekart is not making sure that their delivery guys phone number is active or not. I am unable to get any response from these people. How can they be such careless.
