South Western Railway — cashier did not return back the money

Respected railway manager,
Southwest railways.

Dear sir, i booked ticket from yesvanthpur to hassan on 28/11/17at 1:00pm. Gave 2000rs note to the cashier, total amount of ticket was 355. 00rs but she returned only 145rs to me. After boarding the train i noticed that she should have given me 1500rs more.
Trying all customer care numbers of yesvanthpur railway station but no number is working.
This is not complaint but it's a request to the railway manager to please help me with this issue and help me to get my money back.

Thank you.
Mr. Gangadhar mathpati
