I have traveled from agra to gurgaon through uber cab. At the time of booking fare was shown as 2539 excluding toll and taxes. During the trip 415 rs toll was paid by the driver. However, at the end of the trip driver charged 2250 extra, in addition to 2539 and 415, saying that 750 rupees state tax applicable for every state we travelled i. E. U. P., delhi, haryana. I told the driver to produce the reciept but he denied saying it is paid online.in this regards complaint was also registered with uber but neither they refunded my money nor they provided the receipt for the tax paid for all three [protected]@750 each.
