Easygotrip.com — Ticket cancelled - no refund received

Address:

Hyderabad, Andhra Pradesh

I booked an air ticket on 250.7.2015 with booking ref ET 63967 for travel from hyd to delhi on 3.9.2015 and the fare was promptly collected from my card. but the airline rejected the booking due to fare change and agent did not inform me through sms alert or mail but put the ticket in my account login with the company. on the date of travel, the airline viz jet airways could not locate the booking and i had to buy the ticket across the counter for double the price. i made frantic calls to the call centre, sent mails to team manager and also had an online chat - but the refund so far not yet received. how to proceed further ?
