Air India — excess baggage extra charge

Address:	New Delhi, Delhi, 110030
Website:	Air india

Iam a student iwas travelling from delhi to dimapur yesterday by a connecting flight where i had to change my flight in kolkata, i had excess baggage of 4 kgs and its 400rs per kilo. Whereas they charged me 3200each that was double.. I have never paid such high amount for 4 kilos in any other fligh before i tried to ask those employees they said that's how they charge for two flights but it was a connecting flight. And i never paid extra money for excess baggage. We're they fooling me or is that the right amount i had paid.? If that's how they charge i don't think ill ever travel by air india.
