VODACOM'S SERVICE IS SHOCKING TO SAY THE LEAST!!!!

I have a querie with Vodacom accounts department as they want to bill me R14000-00 the end of August which is totally incorrect as the amount should be around R7000-00 or less. The problem is that you can only call to resolve any queries and there is no physical office or person to see face to face. Some of the call center agents are clueless or rude and others promise to follow up and get back to you which never happens. it is extremely frustrating trying to sort my account out in this fashion. when you request to speak to a senior person you get blocked there and then. i have requested email addresses for senior management and get told they don't have their email addresses. This is extremely frustrating as i must now just fork out R14000-00. Vodacom's business model as become exactly the same as Telkom which is a disaster. i have been a client of Vodacom's since they opened their doors....same number and not one debit order bounce but it obviously means nothing to them. VODACOM CLEARLY DOESN'T NEED MY BUSINESS!!!
