Vodacom sucks

If I could give NO star at all that would have been more accurate!!! Vodacom is *****ing data. My data on my wifi router is running out like water from a tap. I logged a complaint and the call center told me that someone will call me back in 48 hours. I am still waiting. I called again this morning, just to hear that an investigation has been logged and it takes 7 to 14 days to reply. Now that is the worst service ever!! I asked the lady at the call center why it takes so long and she rep**** that I must understand, there are many complaints. So by saying that, she actually admitted that there is something wrong. I then asked to speak to a supervisor and guess what, they are all in a meeting!! How convienient. My problem is that, as soon as I load data, it vanishes within a few seconds to a few minutes. My router is off. The moment I switch it on, my data disappears. But Vodacom refuses to take responsibility. They keep on telling me the problem is with my computer as there are many ways data can disappear and data can not be ****** on the side of Vodacom. Looks like an inside job to me.
