Capping your account a joke

<p>Good day</p> <p>I opened a contract at Cell C in May. I explained to the consultant it is for my son and account must be capped at monthly subscription fee,<br />the lady helping me said they can only cap it at lowest with an extra R 50.00. I capped it at at an extra R 50.00 above the monthly subscription<br />fee after telling her I don't want any nasty surprises at the end of a month she assured me it wont happen. Surprise surprise end of August I <br />received a bill for R 2 127.00. I queried it with the call centre as to how this can happen if there is a cap on the account the lady then threatened<br />me she will black list me ext. ext. I went into the store for more answers surprise surprise again the consultant that helped me don't work there <br />anymore. Apparently they cant cap data only airtime - this was not explained to me at all. To make things worse the account works in a month in arrears. I will be getting another bill at the end of September for R 3 700. Is this even legal in terms of the credit act and what people can afford?<br /> <br />Kind Regards</p>
