Indigo service is pathetic. They charge unreasonable. If you want to cancel a ticket just make sure that you know all the terms and conditions. Because the refund goes to your credit shell with Indigo.
And next time when you want to utilizer that shell amount and book a ticket with Indigo, they charge for that also. If you ask the reason.....the reason is that they are providing you service by booking your ticket on phone. Which airline does that.....ONLY INDIGO!!!!!
BE CAREFUL before YOU BOOK YOUR TICKET with INDIGO. THERE COULD BE HIDDEN EXPENSES!!! THEY ARE UNREASONABLE & PATHETIC AIRLINES!!!!
