Refund not given even after close to 2 months

I have booked the bus in Yatra website using the gift voucher. Then I had to cancel it due to unexpected situation. Cancellation was done on April 24th. After that I have emailed & contacted their customer support almost 20 to 25 times. Whenever, I call they used to say the refund would be processed in 2 to 3 days. But so far nothing has been done. Pathetic service I ever received from a company to their customers. Irresponsible team they have . I stopped following up with them as there is no point in doing so. I will never book anything in Yatra going forward.
