Bad service as usual

i purchased 500mb of data in my june billing cycle .<br> At the begining of the july bill cycle i had over 200mb of data remaining , together with the 200mb that i given to me monthly.I also recieve R200 airtime<br> last week i noticed that my unbilled was over r135 and total was R390 So i called in ,spoke to a consultant who told me that my balance is R290 and the total might not be reflecting the discounts. <br> I still could not belive that i used over 400mb and R200 airtime and R135 in the same month as i hardly call out of my cellphone and use wifi at home. I then asked for an itemised billing( for which i am still waiting)<br> Only to then realised that the consultant had confused my balance due with my unbilled balance.<br> I sure that the itemised billing is going to be for the wrong month. <br> Could i please get help from someone knows what i require. <br>
