Bad Service!

Hi<br> <br> my query is related to cell No.***<br> <br> On the morning of the 18.08-15.I called MTN customer service (***) requesting to update my contact details as I have moved residence.I have also requested that they send me invoices for June, July & August which I have not yet received. The lady told me that I will be charged R18.00 per invoice which I agreed upon.I waited until late afternoon and still have not received any invoices.<br> <br> I called the Call Centre again that same day when a guy answered. I told him that I have called in earlier that day and requested the above. when he looked on the system he saw that the lady left a note on he system of what I have requested above and also that I was charged for the 3 invoices which I still yet have not received! I told him that I have not received anything and how can they charge me for something that I did not get! he put me on hold and then cut me off!<br> <br> I called again the next day 19.08.15. spoke to another lady! requested the above yet again and she promised that I would get my invoices by close of business that day. I STILL HAVE NOT RECEIVED ANYTHING!!!<br> <br> can someone please help me with this simple request.<br>
