[Resolved]  Ezeego1 Travels & Tours Pvt. Ltd — After 50 days I didn't get canceled flight refund

Hi
I booked a tickets for 4 persons from Mumbai to Kolkata through ezeego1. Booking reference no. is EZR[protected]/A
Flight was scheduled on 21st june.
The flight got cancelled by airlines itself. Ezeego1 refunded partial amount on 5th July.
3300 rs is still pending with him. I called them many times and sent so many mails. Each time they accepted their fault and assured me about refund within 3-4 working day. But no refund as of now.I have all proof of mails and the request no's also.
complain request no's are ...
60548
62675
65116
It is already 50 days.
I called so many times and each time they kept me waiting for 30 minute on average for verifying details and those calls cost me so much. And I paid credit card amount by myself after borrowing money to avoid huge fines by credit card.

What should I do?
