Ola Cabs / Ani Technologies — more money demanded

We travelled from sraddha lake front apartment, to commercial street in bangalore on 4th dec. At 5.30 pm. Ref. No : crn[protected].
Driver name : vishnu kumar n. A.
After reaching there he demanded more than rs.470, which i paid in cash. But later i received an email with amount of only rs. 398. Please investigate and let me know. I do not recommend this driver. Thanks
