Sastiticket.com — Didnt received refund

To the readers and sastiticket i had booked a ticket from Hyderabad to Delhi of which i had the ticket and when asked for refund the told me to email from registered account which transaction screenshot and bank details so its been 20 days they have still not initiated my refund and now they are not even answering my calls so when i searched over google about sastiticket it says India’s new emerging company but i dont think you are because the company where there is no customer satisfaction will not go beyond so i suggest peopleand my readers to go for other online company for booking a ticket rather than sastiticket
