Terrible customer service

I am having no joy with MTN. I have been trying since Friday to get hold of someone who can help me increase my data package, but the branch at Galleria was not able to help me and said that this particular department does not work on weekends. I then waited until today (Tuesday) and went to the Bluff branch and had to wait on the phone for over an hour to get a response. The lady informed us that she would get it sorted out, and now I am able to make phone calls, but still no data increase!!! I cannot believe that in this century we are receiving such atrocious service from a company who is supposed to be a leader in technology. Wake up MTN!!!
