Ola Cabs / Ani Technologies — non refund of excess collected amount

I used ola booking car micro silver etios driven by dilip b s on 1st jan 2019 from 56th cross rd 4th block rajaji nagar bangalore to hop coms/lalabagh housr main rd bangalore for rs 130. But driver collected rs 230 instead of rs.130. He did not refund excess collected amount despite having contact over phone at several times. Request take action against driver and collect excess amount from him and refund me as early as possible.
