Billing issues just keep on bugging me!

<p>This is the third time Mtn has levied fees that they cannot explain when I follow up with them. </p> <p> </p> <p>Whenever I complain I'm met with sheer incompetence and no proper answer. They keep sending me a statement that doesn't itemise what it's for. I was in arrears and had to pay everything up to date prior to upgrade, which I did. The upgrade was a mess, me being put on the wrong package. Now that this has been resolved, I'm met with a line disconnection due to an outstanding amount that they insist is for service, but they cannot describe what services?! </p>
