I booked ticket on 13th Jun 21 for Chennai from Delhi, but ticket got cancelled by Travolook, however amount deducted from my account. They accepted it and replied that amount will be refunded within 7 to 10 working days.
I am calling them frequently at every 10 working days for my refund amount Rs 14, 017/-, but they always replied, refund is in process.
