Spice Jet Airlines — baggage

The baggage was little over the limit with 0 hang baggage. Then decided to take out few clothes from the bag to match the limit, but was not allowed to and was charged 2000 rs for the same. Having boarded the plane huge bags were brought in by the fellow passangers which would not even fit in the overhead, their luggage was not charged and was accomadated easily!
This is not acceptable if someone is being charged and not allowed to do something then the rest should also be allowed to do so!
