Spice Jet Airlines — immature communication, horrendous customer handling and service

I have not had to use the word 'horrendous' ever while referring to an experience with an airline.

On 22nd february 2019, upon arriving at the chennai airport, for my flight to delhi (Flight sg 104; confirmation number (Pnr):n5kvky), i realized that i had very little time left to check-in because spice jet had, on a short notice, pre-poned the flight 15 minutes to 645am departure. There was chaos because many passengers, including me, were left flustered and anxious. The airline had informed passengers about this only the previous night late at 830pm by an automated email.

Panicked and anxious, i tried to get ahead on all queues so as not to miss my flight. Upon boarding the plane, i realized that my phone was not handed back to me (At counter no. 8) after checking for the e-ticket on it. I sought help from the plane crew but very little help came through. I was passed over from one crew member to another. I was then passed over to the airline ground staff (Just outside the plane), who requested me to go back to the plane crew. I begged the plane crew to act and help me out upon which i was told that the phone was not found at counter no. 8. All this while, i was using a fellow passenger's phone to call my mobile hoping that it would be answered. The plane crew did not bother to offer any comfort or assistance and only when i pushed them for advice, i was told i could either de-board the plane to find the phone or write to the airport upon reaching delhi. Could i have expected to receive help over email when i could not receive it in person? I decided to de-board.

It was already 645am (The new scheduled take off time) when i deboarded and the plane was far from taking off.

Within 20 minutes of de-boarding the flight, the airline staff (Azarrudeen mohammed j) found the phone at counter 8 and handed over to me.

I approached the spicejet counter to request a seat on a subsequent flight but was told the two flights were all booked. I spoke to a senior airline official at the airport and i was told the airline did not really plan to fly sooner but wanted to have passengers arrive at the airport sooner owing to vip movement in chennai.

I had already lost inr 8.5k, what i paid for the flight and had to book another flight on a different airline for 13.5k to still be able to attend an important meeting with a central government official.

Does it make sense to inform the passengers of a preponement at such a short notice only by email?

Why create panic and chaos by preponing the flight at short notice and still not be able to meet that time? That is incompetent and unprofessional.

Is it even sensible and professional to disguise a request to passengers to arrive sooner as a preponement of flight? How the airline handled this is totally immature.

How did none of the staff at counter no. 8 or adjacent counters heard the phone ringing loud (I made 13 calls on it)?
Did the staff even actually try to find out if the phone was at counter no. 8? Did they make an honest effort? The phone was eventually found at the same counter.

I must be compensated the price of the new ticket or be provided a free open ticket!
