Incorrect Billing and Lack of Service/Resolution

<p>I hate dealing with MTN. I wish i hadnt renewed my contract with them and opted for another provider instead.</p> <p>I renewed my contract three months ago and noticed that i am being billed an incorrect amount to what was agreed when i did the upgrade. I called in so many times but my query is still unresolved. I was first asssisted by Thato Seboka who advised that as a corporate client, the discount on my package hasnt been app****. He asked me to send a copy of my payslip, which i did but nothing was done and no feedback was provided. I then called and dealt with Mbali Ntuli who just doesnt know what she is doing. I am not sure if she is new of what, she kept mumbling on the phone the whole time and after the call she sent me a copy of the charges on the phone. I rep**** to her email to tell her that the problem is that there is data charge on my phone which i didnt authorise and that the 16% corporate discount hasnt been app****. I sent her a copy of my payslip as well but to date i am still waiting to hear back from her. I called again this morning and asked them to remove the data costs as i didnt authorise this on the new contract. Can Someone at MTN who knows what they are doing get back to me to resolve this?? I am serioulsy annoyed and irritated by this kind of service.</p>
