I requested itemised billing for invoice

I requested itemized billing for short messages on invoice dated 13/10/15 (R 394.80). I didn't receive it and had to follow u several times. <br> When I eventually received it, there was still no itemized billing explaining the cost. I once again phoned a few times, with no satisfactory answer. Every time I received different reference numbers. <br> When I received my statement dated 13/11/15, I saw that they billed me 3 times for the same query: <br> 21/10/15 R 18.86,<br> 21/10/15 R 18.86 and again on<br> 22/10/15 R 18.86.<br> When I asked Bongi she said the billed me as it was different requests!! (Ref ***) IT WAS NOT. <br> I am STILL WAITING FOR ITEMIZED BILLING for the amount of R 394.80 on my invoice dated 13/10/15...I want the date and numbers to whom I have send sms's to that value. <br> ALSO, I want to be credited for the R 18.86 times two. I'll pay for this ONLY once EVEN if I received a report that is not itemized billing. I even asked them to explain to me this so called itemized billing and they could not. EVERY time I enquired about this, promises were made and different explanations was given every tome!
