After 5 months im still being billed incorrectly

<p>Its been 5 months now and mtn is still not billing me correctly. After calling in multiple times and speaking everyone from managers to call center agents, and being promissed that this would be sorted out, MTN has up to now still not corrected my invoices and statements and has now sent me sms's stating my line will be suspended. Its shocking how bad the service is and that the people employed at mtn are this ***********. &nbsp;Everytime i call, i have to hold for 30min or more and then the agents who assist me just keep telling me they have logged a ticket through to a different department which nobody can call as they dont accept calls!!!!!</p> <p>This is the worst customer service i have ever recieved and my third complaint about the company on this site. Im hopeless as i dont know where to turn too to get this sorted out.&nbsp;</p> <p>&nbsp;</p> <p>Cornel smit</p> <p>***</p>
