Indigo Airlines — Unethical behaviour at kolkata counter

We were travelling from bhubaneswar to Kolkota by flt. no 6E 557 and then from kolkota to Guwahati by flt. no 6E292 on 19/11/2015. Dep. time was 4.10 pm at kolkota. we were four persons with three hand bags of total 13 kg weight. one of the hand bag was 9 kg. The on duty young lady who issued boarding pass no 5ABCD did not allow as hand bag rather she argued very badly. she was very rude in her behaviour. Such type of rude behavior will harm your noble profession.
