Indian Railways — ticket counter staff

On 8th april at 9.30am i booked 6 adult and 1 child for arambag (Hwh - arambag local) from howrah station counter no 11 (Ladies) i gave him 500rs note and was shocked he (Sirdhatha chakravarty) charged us double by providing with return ticket which i didn't ask. When i pointed out hus mistake he didn't pay any heed after that started using offensive language and totally denied his mistake. I immediately rushed to the deputy managers cabin but he could not compensate with our lose.
