Taxi driver fraud

Description

I took a taxi from borivali station east for thane, after reaching there he asked for night fares even it was day time, after 5am, asked for 70 rs toll, although he didn't paid the toll, just used a name to avoid toll, and most important i gave him 2 notes of 500, he quickly exchanged one with 100 rs note and said i have only provided 600 inr, i have read about this incident many times, so i knew about the fraud, so i checked again and found my claim correct, so after the intervention of security guard over there, the taxi driver went away. too bad i didn't noted the taxi number, it was maruti van
