Poor service

A few months ago I had an issue with Vodacom's ticket data that I bought, but couldn't use. It took Vodacom two weeks to fix the issue (and I had to phone several times, just to hear their apologies and promises to fix it). Now my oldest daughter is also having the same problem with the Vodacom ticket data. A week ago I went to a local branch, thinking that it would be resolved faster, but yesterday I had to go to the branch again to log the issue. I doubt that it will be resolved. And this morning, my youngest daughter told me that she is also unable to use her Vodacom ticket data. I don't even have the energy to try and phone them and listening to their empty promises of fixing it. And I don't have the time to go to the branch again, because they are just as clueless. Maybe I should switch to MTN or Cell C?
