Misleading information and bad service

I called 082 155, to buy once off bundle, as I've received sms'e that my data is almost finished. I wanted to buy 3G @ R299 and spoke with Musa. She asked if I want it over 30 or 90 days. I asked what the difference is. She didn't answer me and load the 90 days. I then asked her to please check my balance as I just got a new phone and don't want any surprises. What a surprise!! My account for next month is R3 800 due to data of R2 720 that I've used TODAY!! I asked her to send me the detail of that and only received the one amount next to today's date. I requested to log a dispute, as I've been at work the whole day and did not browse on the internet and I've switched my data off when I received the warning sms'e. She put me on hold for more than 15 min without giving me a REF number. I hang up and call 082 155 again, but reached another contact centre with no Musa. I spoke to Mpho who really tried to assist. She looked on my account and noticed that 2G data was uploaded today. According to her, 3G over 90 days cost R350 EXCL VAT!!! That is misleading information. Mpho promised that Kabelo will call me back. I still have not logged a dispute regarding my high data bil
