Ola Cabs / Ani Technologies — incorrect cancellation charge

I ordered an Ola cab at around 16.15 on 18/6/2019. I immrdiately telephoned to speak to the driver as I realised it would arrive too early. I cancelled the taxi and told him I would book one later.

A few minutes later I received a message stating that my taxi had arrived. I called the driver and asked why he had still turned up after I cancelled. It was only then that he told me that he wad unable to cancel and it was down to me to make cancellations. I have been charged a 4 pound cancellation fee and would like that put back into my account as a matter o[censored]rgency.

Also, I have booked taxis with Ola cabs and received messsges stating that the driver has cancelled... Really???!!!
