National Travels — dropping point

Dear sir
I booked a ticket from bangalore to chennai for date 23 rd december with ref id[protected]after telephonic talk at[protected]. The person told me to drop at airport only at 11.30. Today the driver missbehaved with the passenger kasturi mantri seat no 19. Just now she had a drop before koyambedu. U are now requested to pay rs500 for coveyance. She has a flight scheduled at 5p. M. She is in trouble.
