Address:

577102

I reserverd 3 tathkal tickets with pnr:[protected] from kadur to belagavi for chalukya express, train no 11022, with date of journey[protected]. Though at the time of booking available berths were 105 and i have specified lower berth to my grandmother who is 80 years old with left side hemi-paralysis, still she is allotted with side upper berth. Re-allot her with lower berth to travel comfortably
