Ready to change service providers!!

on the 28th of August I called MTN Customer Service and Requested them to send me Itemised billing that will show me calls & sms from 15-31 July 2015. Spoke to Natasha REF***,who explained that I will need the June,July, August Itemized billing in order to cover the dates I have requested, fee to be charged R150. I was advised that it will take 72 hours to receive the copies of the billing. Nothing came, I called back spoke to Aneek REF*** who promised to send the same and ...nothing I have since spoken to ESihle, Robin (he sent me Sept which I am charged for ), Claudine, Lulama(20 Oct) managed to send me the Itemised billing while I was speaking to him on the phone, however I received itemized billing from 28 August onwards. On the 28 Oct I spoke to Maralisha who was clueless, I asked for a supervisor, no one was available but however she said the supervisor on duty will send me the itemized billing.....I am still waiting. On the 29 Oct I spoke to Palesa....I am still waiting!!!***** and above this I was being charged BIS since 2014 yet I do not use a BB, REF *** is still being investigated? I need this resolved & my REFUND !!!!
