No Follow Up - High Bill

Good day, I lodged a complaint previously and i spoke to Mpho who was very helpful, however he referred some guy from the data department. I was sent a data report of which did not answer any of my questions. i still dont understand how do i get charged from checking balance on my modem without logging on to the internet. I advised the same guy that i did not understand, he said he will call me back, till this day i have not been contacted back. I dont understand at all what that reports means and it feels like i'm being pushed to just accept the charges. Can someone please call and explain what the data report is supposed to mean in laymens terms, i cant afford to pay the R1999 bill charged, i dont work anymore.
