Indigo Airlines — Booking error by customer care executive of indigo

Address: Mumbai City, Maharashtra, 400059

Under PNR I6N5NY, the ticket was booked for BOM-MAA on 18th and return on 20th for 3 pax plus 1 infant. On 27 April I changed the return sector MAA-BOM from 20th to 22nd by paying additional payment Rs. 9809 with the help of call centre executive. Today, the 22nd May at the Chennai airport child was denied entry saying the fare is not paid and had to pay Rs 1000 additionally. All this incident put us in a very very bad embarrassment over the counter for NO FAULT OF OURS. from the booking if you notice that we have paid CHG2 for 3 pax and 1 infant Rs 1000 - still Indigo staff says payment not made. It is Indigo customer care who has changed the booking and asked me to make payment using IVR. Will you please investigate this matter and let us know who is at fault and what action you can take to save our credibility and now it becomes our prestigious issue. Awaiting your favourable reply.
