Fed up with Vodacom and there empty promises.

You buy data bundles from Vodacom but can't use the data. Call them tell them this has happened before they tell me switch off your phone after 10 minutes bundles will be working. What about data already lost due to your bundles not working? Call again seeing its not working still. Now i get told the sup will call me. Well well guess what i still haven't receive a call. And data bundles still not working. Try to contact them again with no luck. Vodacom *****s from its clients and its improper business tactics. Why must the people pay for your ***** up system?
