Dear sir,
This is to bring to your kind notice that, we booked ticket via Tatkal from Bangalore to VANIYAMBADI train No. 22626 on 07.05.17, belonging PNR No. [protected]. On coach which we travelled there is malfunction of air conditioner. The total journey was without AC. There is lot of suffocation with out air and too my wife is pregnant, she suffered a lot with out air flow. We paid lot of money for travel but of no use. I request you to take immediate action and refund the amount.
