Air India — Alphabet restriction on flight booking portal

Address:

43/18 dream house 8th cross street, west shenoynagar , chennai 600030

Reference: Booked through Make my trip India PNR No: KLQSQG E ticket no: 098-[protected] Date of Journey: 24 Oct 2022 from Chennai to Singapore & back by Air India.
Name of the Passenger: Balasubramanian Chandra Sek Bharathi

I had booked the above ticket for the journey from Chennai to Singapore and back for me and my wife. My name is "Balasubramanian Chandra Sekara Bharathi as it appears in Passport. As per Make my trip booking site Air India restricts given name to 27 Alphabets. Hence my name appears as " Balasubramanian Chandra Sek Bharathi ". Realizing this discrepancy Immediately raised a complaint to Make my trip (complaint no[protected] and air India (case id[protected] through their customer care no. Both the agencies are now saying that i have to cancel the ticket and rebook it. As i have booked the cheapest nonrefundable ticket i have been put to a financial loss for no fault of mine.
This has put me to enormous amount of mental and physical stress in addition to financial stress.
As a senior citizen my effort to explain my predicament to both Make my trip and Air India executives of the two agencies has been futile so far.
