Vodacom feel nothing for wasting Clint’s time and money

I went to Vodacom in Northgate to upgrade, I was sold the wrong cellphone cover, when I realised it was wrong I went to Vodacom Cresta who refused to assist, I owned a CTM franchise and if you bought somewhere else we assisted all clients, I then drove to Northgate at considerable time and cost snd when I asked for a discount to cover my costs for their mistake I was told the manager was not at store, why do clients always pay for staff incompetence and for our waste of time, over 30 years as a client paying monthly without a problem and I am treated as someone who is nobody, well done vodacom
