*****ing Money - THE WORST CUSTOMER SERVICE EVER!!!!!!

It has been exactly 3months and 2.5 weeks since my numerous requests to give me feedback on our Business account. One of our conracts suddenly has high data usage since Apr 2017 to current. Even though this conract has a data bundle. We have been to a Vodacom store 3 times to have this matter resolved and explain what is causing this excessive data charges & nothing came from it, then I emailed my request to customer care on the 7th of August to provide me with sufficient proof. Since then I received the same report 4 times from 3 different people that is an xcel sheet with "0" digits. I have been sent from the one person to the next, and no one can give me an explanation on why are we charged such high amounts for data. Yesterday I received a phone call from a vodacom employee (Ronald) asking to put my request on a letterhead and email it to him. This is now my initial request sent on the 7th of Aug!! Yesterday he sent me the exact same report sent previously after I explained to him over the phone and on the letterhead what exactly it is we need. I rep**** this morning highlighting it for him and explaining to him what I need, he did not reply. Now I received another mail, from another Vodacom employee (Bongani) saying I must email my request to someone else.....This is unacceptable customer service. We cannot accept unexplained high data charges on this nr and we can not accept being sent from port to starboard with no answers. Vodacom is *****ing data and charging excessive amounts that we must just accept. If we are at fault we need to know about it. Sending us a report with no info on is not proof that we used the data for what ever the case may be. #VODACOMMUSTFALL
