Wrong destination

On the 7th of August I had a meeting at the WRSETA head office in JHB . i took a taxify from the Gautrain Centurion the driver took me to the address I typed in and we seen it was not correct then I had to reorder the taxify I put in WRSETA which came up with the correct address and the driver put the same address on his GPS but he took me to another location at Deloiite and Touche we passed Sandton and on my Taxify app it was showing that we were moving away from the destination I told him and he said he is just following his GPS and he insisted he followed his GPS but he didnt take me to my destination. I missed my meeting I incurred so much of costs travelling form Durban to JHB when I queried this with BOLT they just said the driver took me to where I wanted to go its not his problem if it is the wrong place I actually paid him for taking me to the wrong place Taxify is absolutely appalling with their customer service I want all the costs that I had incurred including my flights and train and taxify costs .I will be taking the matter with my legal representation .
