MOST PATHETIC CUSTOMER SERVICE

I have requested to have my billing sent to me repeatedly. I have called their call centre 10 times and still, I am sent the incorrect invoices. How difficult is this to understand. Is MTN going to pay me for the time I am wasting each time and have to request the same information over and over and over?? Who else can I call as it is clear the call centre doesn't have the comprehension to do a simple task.
