Indigo Airlines — Excess baggage charged for cabin baggage

Address: New Delhi, Delhi

My daughter was traveling from Varanasi to Delhi on17.01.2015 and she was charged Rs 1500 as excess baggage as the cabin was not upto dimension. Please note that she travelled from Delhi to Varansi on7.12.2014 with same cabin baggage and she was allowed to take the luggage in cabIn . Pl.clarify as how the rule differ at different Airports. Also due to rescheduling of flight, she could not appear an inertview and lost the oppurtunity of getting good Job. I thereby request you to reimburse the amount of Rs.1500.Also compensate suitably for loss of opportunity of good Job.
