Billing Gone Wrong - Terrible Customer Service

<p>I recently upgraded my cell phone contract and signed for a Samsung my choice 100 @ R689. Since taking up my contract I’ve been billed R1200 and everytime i call the call center i get told "i cannot be assisted". The lady that helped me sign the upgrade, Lee Andra Marks at the SABC0952 MTN Store - Wanderers Building 57 - Bryanston (Dimension Data), assured me that the issue has been resolved and i will be credited the 3 months that i was incorrectly billed. She promised me that month ending March and April, i will not be debited. At the end of March i was debited -539.02 and when i called her to get an explanation on this, she said she would AGAIN investigate. She went as far as saying if im not happy with her efforts i should log a complaint because there's nothing else she could/would do. Which in short meant "tough luck, deal with it".</p> <p> </p> <p>I need someone to tell me why i shouldn’t just cancel this contract and move to another ISP or why i shouldn’t just stop all payments until all the monies i was incorrectly billed. Can someone get on top of this and FIX my billing. Because clearly Miss Marks, the person who signed me up and promised to resolve my issue, has more pressing issues to worry about, like pushing for commission, as opposed to attending to the mess she created.</p> <p> </p>
