I have chosen berths U20, and U21 to travel from Bangalore to Cuddalore. AC ventilation was open above my berth, due to which entire AC flow was on us, hence we felt very cold, and when we reported to staffs, they have given me blankets, however it was not enough to withstand the cold and noise coming from AC vent. then we switched seats, to U24 and U25, only available berth during our travel.(that's what they said) since berth was having TOP Ventilation for air, due to rain water droplets were coming from top and made my bed wet.
we are paying high fare, because of convenience, but we had a bitter experience. I am gonna file complaint, if there is not action taken on this.
