Air India Express — Feel Cheated

For your information & Necessary action
I purchase direct flight ticket from Abu Dhabi to Mangalore With PNR no FKWGVT(Attached ticket for your reference).Flight Details mentioned in attached file.
IX816 was suppose to fly on 1st of July 2021 2345hrs but delayed.However after 5hrs of waiting the flight take off at 0500hrs on 2nd July 2021.
For my surprise, while landing the pilot announced that within 5 minutes we will land to Calicut airport.I was totally shocked & feel cheated how come it was Calicut airport, oh my god it was shocker of my life instead of manglore flight landed at Calicut airport.After waiting for an hour at Calicut airport finally the flight IX816 reached to it's original destination at 1205hrs on 2nd July 2021 that is on Friday.
Please look in to this matter & do the needful.
