Ekart Logistics — delayed delivery of my order from flipkart

Address:

Ekart logistic Bhiwandi delivery hub, Thane, Maharashtra, 421601

Delay of delivery of my order from ekart logistics. I ordered a sleepwell mattress. Promised delivery date was 14th august, my order was out for delivery from 14 august but i didn't get it. I was called the provided number of delivery boy, he said he will be deliver by same day, but he didnt and when calling him he blocked my number. On 16th august i recieved a txt msg from e-kart logistic, that they will deliver tomorrow means on 17th of august but they didnt delivered till now. When i was called the flipkart costomer care they asked me a time till 19th august to resolve my issue, but they didn't. After that they asked me to wait till 20th august for resolution from their end. I was not recieved any resolution or my product from them till today. Everytime i call the customer care they asked me to wait 24-48 hours. Every time same reply from them. Even i am unable to cancel my order. My order is prepaid by credit card, which emi was converted already. I have sent many mails to them but no reply. Kindly solve my problem and deliver my order as soon as possible. I am so disappointed by this delay of delivery of my order.
