My bill is almost 3 times more than usual

I've had an issue with loading data on my phone.<br> <br> Contacted customer care, several times. No answer.<br> <br> I've send an e-mail to customer care, received an confirmation e-mail but, until today not contacted any how..<br> <br> I can not believe that 2Gb of data can be +- R 800.00...<br> <br> The can't get back to a person, but don't hesitate to deduct the money.<br> <br> <br> <br>
