railyatri.in

I've booked a ticket (11/10/2017) using rail yatri app from rampur to badshahnagar, train# 13020. Further details are: order id 158199
Ticket amount - rs. 433.07
Ticket cancellation amount : rs. 290.0
Net refund : rs. 290.0
During reservation, it was 280&281 wl, which later on journey date (14/10/2017) becomes wl 38 & 39. So finally we didnt had any confirmed seat as chart prepared so we didnt travel. And according to policy, if ticket not confirmed, the refund should be 100%. But we received less. We want our money back.
