Frustrating and shoddy service from the “best network” Vodacom

I mailed relevant to Vodacom to change surname after I was given what was supposedly the correct email address for that. An email was sent to me saying I needed to have a service request reference number for them to help me. I called Vodacom again asking what that was. Got it and mailed again. When I got invoices and saw changes were not done, I called again. I was put from pillar to post with looong waiting periods before I could speak to someone. Two of the people I spoke me told me to go to the branch to do the change. I DON’T have time to go to the branch. This is so archaic, we live in the technological era. I can’t be expected to leave my job and drive to a branch because people are lazy to do what they are hired to do. The last person I spoke to said I was being hostile to him when I told him that no, going to the branch was not the easiest way of doing this for me. It is tedious and interferes with my work time. Then they have a nerve to waste more of our time by requesting us to stay on hold to rate their service???
