Travolook — Auto cancelled the ticket and not refunding the money

I have booked a ticket from COK - DEL on 21-JUL for my mother. The money was deducted, however the ticket confirmed and then got auto cancelled.

They told me that in 10 working days the refund money will be dispersed.

I have been calling them repeatedly but they always say that it will take another 6 working days.

Even the mail is bouncing.
