Konkan railways

We had booked 18 ac tickets on 11th of june to goa from mumbai by the jan shatabdi express but we had to travel in general category as there was no ac coach due to some technical problems. The tc had assured us of a refund at the time. Our travel agent had booked tdr request on the 17th of june. I am in constant telephonic conversation with mr sachin yadhav who is only assuring me of a refund since the last one year.
