Worthless customer service

I received a confirmation email for the hire of a Mercedes Vito for the 23 September 2021. I called the Cape Town International branch manager and he confirmed my booking was in place. When i got to Woodford, myself and two other customers were told that the Vitos we booked was not available and we have the option of hiring a GWM double cab or two Toyota corrollas. We were then promised that the Vitos will be delivered the following day at our destination, this did not happen and when i called the Branch Manager he promised the vehicle will be delivered on Saturday. I tried calling him back and he did not answer nor return my call. A similar message was sent to the Essa Suleman the MD of the grp and still no response. Please don’t bother to respond as it will be another lie.
