Air India Express — Boarding Pass was denied.......

Address: Chennai, Tamil Nadu

My son about to aboard from Chennai to Colombo on 21 of Nov, 2013 but he was denied giving boarding pass by asking him to pay Rs.2000/- for excess baggage. He was carrying only 24.5 kg totally with hand baggage. Normally 20+7 allowed. We are very much doubtful that there is some fraudulent practices is going on in weight etc. And the wort thing is the counter staff was very rude with perfunctory.
