Call centre have no idea what is going on

As a business we chose Vodacom for our various simcard packages we have purchased. In order to just set up a simple view for our company to be able to see our sim cards and their activity in order to top up and manage the accounts has been a nightmare. The call centre is the most frustrating. No one knows what to do to assist and i promise you eveytime we call the business side on ********** they answer and the call gets cut off or during the call we are cut off. Then have to call again and go via all the options and explain what we need AGAIN. Seriously it is a joke you call centre is not good at all and resolving queries is not good. You need to spend less money on trying to attract new customer and spend more servicing the ones who are already supporting you.
