Account problems with Mixed data

I have 2 mixed data contracts with Telkom, a 10G at home and a 20G at my office.<br> Both are on a debit order, Telkom debit my account and send me a bill. (Huge amounts over and above of my debit order for capped data services!)<br> They load extra data and remove data as and how they wish, went into a Telkom shop to try and resolve -NO LUCK the consultant was not interested at all to assist! <br> The manager Yogen ask me to send her a mail, whereafter she will respond, needles to say - NO LUCK!<br> The most expensive disorganised package deal ever!!
