Exon is the worst cab service I have ever had... Not once but twice... Firstly, the cab came 1 hour later than the time requested and secondly, they sent an old dirty sumo instead of a qualis without informing.. When asked the driver, he said he is not accountable and wanted us to speak to the travels Office and the TRavel office guys they had a whole host of excuses and got very aggressive...Because of them , my family missed the train and this cost me Rs. 6000 in ticket fare and had to book flights owing to emergency which inturn cost us another 15k... And guess what, Exon did not ownership.. INstead all they could do was shamelessly deny any fault
