On my birthday, I got a $15 coupon in my email with March 17, 2023 expiry. I had to book a flight. I found a ticket on the Indian Eagle (IE) website for $408.10. When trying to book that ticket using the coupon, the website gave an error saying that the coupon validity had expired, which means IE issued a faulty coupon. I called customer care to report this issue and seek help. I told them that this is a time-sensitive issue and that ticket prices will rise soon. The agent talking to me told me that their team is looking into this and will respond in 15-20 minutes with a resolution. I didn't receive a call back for 2 hours. I called them again. I spoke with a new agent who told me the exact same thing. As of then, the ticket was still available for $408.10 on their website. I did not receive any callback for 6 hours. I called them again and asked to speak with a manager. By now, the ticket price had gone up to $416.10 on IE, so I tried booking it online. The supervisor denied proper help and said that I need to pay $442.10 for that ticket, which was available on IE for $416.10. I kept asking why I should pay more when it is available for a lower price on IE but he didn't budge. After multiple calls, I tried working with him towards a resolution but he forced me to pay via Zelle instead of accepting payment via their online payment gateway. Again, I had to make several calls to them to try and reach a resolution. Next, they demanded an email from me that I would not request a chargeback, even though I have booked with IE before and have no history of chargebacks. As of now, I have 2 pending bookings with IE (along with my credit card info) that they are neither willing to confirm nor cancel. I and IE have evidence of all these claims as screenshots and call recordings. I would like for some authority to review these demands from IE and determine if they are legal and ethical because it looks like a business trying to coerce a specific behavior from a customer.
