Ola Cabs / Ani Technologies — Harassing with multiple call to pay the due which I never used

I am getting multiple call from OLA to clear the postpaid amount of Rs120.00 since a very long time. I have raised multiple concerns with the OLA team, however there is no response from them. Now I started getting calls that my CIBIL will be impacted and they also have my contact list and they will start contacting them regarding the payment. Also stating that some agent will come and collect the amount. I am fed up with the continues calls and this harassment. Please help me to get this issue resolved. attaching the evidences for your references.
