I got double charged this month

<p>Hi,</p> <p>This month I was charged over R1000 which was totally unexpected since as far as I understand - I was supposed to pay R603 this month ( of which R100 was penalty for not having enough money on my account - since last month I had no way of seeing how much they would charge me - the amount I had was apparently short of what they took ).</p> <p>To be able to see how much the exact amount for each month - I am trying to log into my vodacom account online but for months now it gives me errors and I am never able to log in. When I talk to customer care - they told me " sorry they made a mistake" and nothing else can be done about it.</p> <p> </p> <p>Every time I call customer care - a new story and amount is given as explanation.</p> <p>I specifically went to the shop to find out what they say - they told me that this month R603 will be taken off - but when I went online today I saw the amount taken off was over R1000.</p> <p> </p> <p>How could I ever be sure what is actually my monthly amount? How can a company double charge and say "sorry it was a mistake" - and why is it that when I contact customer care - each person I talk to - gives me a different amount - when I ask for my exact monthly fee. And finally why can't I actually log into my online account to follow all amounts and info about services rendered.</p>
