Vodacom incompetence

Yesterday morning I bought 2 GB of data on the Vodacom app. 5 hours later 1.2 GB had been used. An amount I barely use in a whole month. I phoned Vodacom and was firstly disappointed in their extremely user unfriendly menu at the call centre. Secondly I was transferred about 3 times before someone could assist me. This person, Keabetwe Kgapane, was incapable of understanding what I was trying to explain to her. If you look at my track record I have never used so much data in a few hours. There must’ve been a problem somewhere. After insisting I want to speak to her supervisor, she disappeared of the line for long periods before saying her team leader, Cedric Manala will phone me back after investigating the matter. It has been 24 hours with not one word from Cedric....

What does one have to do to get proper customer service from Vodacom??? What happened to my data?
