EaseMyTrip.com — My refund of flight booking

I have booked a ticket through easemytrip.com today on 7pm Varanasi to Kolkata dated 13th of march. The amount which i was supposed to pay has been deducted from my bank account but i didnot recieved any confirmation and after calling to the easemytrip helpline number i got to know that the payment was not recieved yet. But after 45 to 50 minutes i got a call from Nikhil Sharma that they recieved the payment and whether to confirm the booking or not. As I already bought a ticket from indigo so i told them to cancel and was informed that i will be getting the full refund after they initiate the process within 5 to 7 working days and i will be notified with a mail of initiation process within 9pm but still i haven't recieved any mail and also i am continuously trying to reach them but the line is busy. So i want some serious response regarding my issue. and the ticket was being booked in the name of Shankhadeep Chattopadhyay and the mail id that has been given during the bookin is [protected]@gmail.com. I am providing all the information so that i will a mail as soon as possible.
This a very careless way of dealing with customers and also very disappointing.
