Incompetence

My data bundle was being consumed too quickly on my Wifi router so I requested an itemised bill to check why. The first person I spoke to asked me to fax my ID and a letter to request it. I did. A week later, no response. I called back and was told I need a reference number but they were offline and would call back. No response. The following week I called back and was told it was not possible to get an itemised bill. I asked for someone who knew what they were talking about to speak to. The person I spoke to gave me a reference number and an e_mail address. I sent the e-mail with all the requested attachments. They respond on e-mail to confirm receipt and promised a response. No response. I called a week later to ask about the request and was told it was closed since they never received the info and sent an sms to my wifi router as confirmation. What a mockery of intelligence. Now they want me to resend the info to the same e-mail again! I give up! Vodacom please hire people who are serious about customers
