Vodacom customer service shocking!!!

This is now the 3rd time that I am posting about the same issue in 1 month and I am fuming!!! Close to a month ago I noticed that my 5GB data bundle was used up in less than a week and a R3000 bill for out of bundle usage. I phone Vodacom almost on a daily basis and every single time they say they are still investigating. How long does it take to investigate!!!<br> <br> I also notice that there are MANY other Vodacom subscribers with the same issue, so it is not me, it is Vodacom. And the last 2 times I posted here, Vodacom assured me that someone will get in touch with me, and still nothing. It is also worrying that since I have logged the complaint, no phone call from Vodacom and no sms.<br> <br> Vodacom, should all your unhappy clients with incorrect billing start with a class action lawsuit before you actually do something about the issue?? Should we contact Carte Blanche? <br> <br> Fix my freaking issue and get someone who is investigating my issue to actually phone me, otherwise you will leave us no choice...<br>
