Cool Cab Taxi Mumbai — Cheating

Beware,taxi commuters in Mumbai.
I would like to highlight my experience yesterday which is making me feel disturbed all through today..Anyway thinking of putting this on the forum so that,at least the one who reads it will be cautious..Now I am also hearing similar stories from others here!
I took a taxi from the domestic airport to CBD Belapur yesterday.Took a cab outside as there was a big queue at the prepaid counter.I hailed a cab (This was a Santro Cool Cab) and asked him for the fare.First he said he will charge by meter. Once I was inside the taxi he showed a printed chart showing rates from Mumbai to outstation places,which showed Belapur as Rs.1200.I said,it is around 650-700 at the prepaid counter.He finally agreed for 900 bucks and started.On the way he was abusing people on the road as well as breaking all possible signals,going on wrong sides,spitting out by opening the door etc.(This is usual practice for these guys).
When we reached the toll booth at Vashi,he demanded that I pay the toll fare.I refused initially but he was adamant on this one and this was not agreed earlier,so I paid.On reaching Belapur I handed over a 1000 rupee note to him and waited for the change.To my surprise and shock,he said the fare is 900 rupees and waved a 100 rupee note to me signalling that I gave him a 100 rupee note and not 1000. I was a bit confused and not very sure and thought that it might have been by mistake as it was dark that I may have handed over a 100 rupee note to him.I took the 100 rupee note and gave him another 1000 rupee note.After taking back the change,I got off the cab..After reaching home,when I counted the money in my purse I realised that I have paid him 1800 bucks instead of 900.
It was too late by then and I had not even suspected anything of this sort could happen.
People,please be cautious...These crooks come out with Novel ideas to cheat.
Finally, one who hard earns the money,feels the pinch and it really pinches very hard.
