Air Asia — rs.220 extra charge for seat at t3 delhi counter

Address: Bangalore, Karnataka, 1100018

Dear concern
Yesterday i have travelled from new delhi to kolkata I5-548.
When i went for check in counter the associate sitting pitched me
“Your seat is unreserved and you have to pay Rs.220 to get the seat reserved”
I somehow paid her Rs.220 and she said that she has given me complimentary meal which was disaster.
Now the Question arises that just for promoting the meal she scared me by saying your seat is unreserved.
Ifeel cheated and dissatisfied with airasia and will think twice before travelling with this airline.
