I took a ride today in the morning from masab tank to banjara hills. I paid in cash to the driver and later they deducte amount from my ola credit money as well.
When I called up customer care to compalint, they mentioned that they cant do anything and when I spoke to their supervisor, he mentioned that driver is denying for the cash payment. I told him to connect me with the driver on a conference call which he denied.
My total bill was INR 55, i gave a 100 rupee note and 5 change to the driver. He returned 50 back to me.
Its not about 50 rupees but its such a shame to have people like this.
