Horrific service from Vodacom

The level of service that I have received so far from Vodacom is absolutely ridiculous. I currently have 5 contracts with Vodacom and absolutely everything that I inquire about does not get resolved or takes forever to be dealt with. ( One would think they would cherish all the business that I give them! ) For the month of June 2018 they have conveniently decided to overcharge me for an amount of around R1,500.00. After just over a week no concrete feedback has been given. ( Which leaves me to pay a grand total bill of R5,500.00 which I am refusing to pay. ) Most recently another issue YET AGAIN with just ordering a sillyTablet on a new line ( seems like they don't want even more of my money that is very strange ) , so much for "next day delivery" when shopping online. In all fairness I have not experienced Vodacom to be as useless in the past but these days I will advise everyone to stay away from Vodacom! Regards, Your high-end irritated client
