Data overcharged by Vodacom

<p>I'm being overcharged by Vodacom data, I always buy my data but the overcharge me between R600-900, extra in data, I've tried querying it for more than 4 months now, nobody can explain why, they ended up crediting me with R1300 but that's not what I want I wanted all my money for all these months, even that credit some others say they've realised they did overcharge me but then someone called afterwards to say it's just a token, I don't need the token I want the money to be refunded back to me and that they stop overcharging me, worse, they keep on delaying to respond and come up with unsatisfactory response. I feel they are de*****ing my hard earned cash</p>
