Asked few representatives and again went to different counter where they were doing weight check for luggage, person informed that it can be taken as carry bag. While boarding, representative present at counter told to pay 500 pesos to carry luggage inside flight after lot of debate I agreed to pay and then other representative told to pay 800 pesos. Finally paid 800 pesos and got receipt They were not willing to listen to customers and behaviour was extremely rude.
