Address:

DADAR WEST, MUMBAI

Dear Sir/Madam,
I have book my airway ticket through your website under BOOKING ID NN2S8ET6JFWMRKW3868.
I book for Mumbai to Paris return flight ticket in Air India. Booking PNR no with Air India was PNR 5J47KY.
Mumbai to Paris (France) was on 21st May 2023 & Return Flight was on 3rd June 2023.
There were 2 passengers, me & my sister. On 2nd June 2023, we tried to reschedule my return flight from Paris to Mumbai but was not able to do through your website or mobile app. whenever we tried to go into change flight timing the website or mobile app displayed error message. Try to call from Paris to help nos but it was also not work out.
After spending 4 hours for it, we have to purchase fresh ticket from another airlines websites and reschedule our return journey.
so we did not use our return journey ticket. we want refund for the same.
Kindly do the same at earliest
Thanks
Hitesh Vira
