Ola Cabs / Ani Technologies — additional fare charges

The estimated fare was shown as rs. 1217 at the beginning of trip from mumbai airport. But driver called me & told pls don't pay at the starting of the trip through gpay as his kyc is not done & pay at the end of trip. I have started the trip at 11.40 pm & he knew that after 12 pm there will be increase in fare charges. At last it costed me rs. 1500 instead of 1200. It could have costed me rs 1200 only if i opted to pay before 12 pm. This should be justified by ola.
