When I booked a cab, and selected the payment method to cash, it said that you have to remove the 50% offer voucher. BUT THERE WAS NO OPTION TO REMOVE THE VOUCHER! Developers, please fix this; or I have to wait till the offer expires. Also, this app is very diificult to use as compared to other taxi apps. puttin the dropping location and pickup location are very diificult in this app. I RECOMMEND USING OLA CABS INSTEAD OF THIS UBER.
