Ekart Logistics — cancelled the order and want refund please

Address: Gautam Buddh Nagar, Uttar Pradesh, 201301

I ordered asus zenfone Max pro m1 yesterday i.e 30th august 2018 from flipkart and it was supposed to be delivered by today i.e 31st August 2018.
and today morning before the delivery of my phone i got a message from Ekart in which i was given a link to pay the price of my Mobile through Phonepe app .
and i paid Rs. 10999 through my bank account linked to the phonepe app.
I also got confirmation message of my payment from Ekart and i was told that if the phone is not delivered due to any reason then the amount will be refunded .
However due to the incomplete address the delivery could not be completed and i cancelled the order but i have not got any refund so request you to kindly immediately process my refund.
