Paying for Itemised Billing getting nothing

I have had itemised billing on my account since I opened it with MTN in October 2015. In December 2015 I logged a call via the internet stating not getting itemised billing, no feedback, so call call-centre in January 2016 to advise that I get a link to my bill via email but when I go to the site under the itemised billing it says I am not subscribed to it. <br> However it clearly reflects as a charge on my monthly invoice.<br> The gentleman said that I was correct it should be provided and he would have the last 3 months invoices and itemised billing sent to me. <br> I AM STILL WAITING!<br> I logged a call via the website in March 2016 with the same issue as it has not been resolved and no feedback.<br> So now I call the call centre again and am told the system is down and I will just have to phone back later as they can't contact me when the system is up.<br> I am only 6 months into my contract and already the service is shocking.
