WON'T LISTEN TO QUERY OR RESOLVE

I have called nearly 10 days ago to try and resolve a query that no one at MTN seems to be cared about or prepared to resolved. My itemized billings does not show the charges for my calls. I carrying on being told that its because the calls came from my package where I have just recently changed over to a package that doesn't provide any call time and just purely for my itemized billing. <br> I asked to speak to a supervisor who wasnt available and didnt have an email for customers what kind of nonsense is that you are not allowed to deal direct with the supervisor.<br> <br> I am urgently waiting for someone to attend to my query. I have received two reference number 135 994 022 and *** <br> <br> When I changed my package over I reiterated the importance of my itemized calls being correctly charged for and this was the one thing MTN couldn't get right after I was reassured 3 times all was sorted!!!
