Overcharged Data Bills

<p>I am getting so frustrated with MTN. Quering my statements of why I am been overcharged, Zukiswa from MTN (req: ***) kindly rep**** (thank you) and explained to me what I already predicted in my previous query that ' charges are validated' (lol). Websites I searched were mailed to me but what I want is PROOF of how it amounted to triple the amount of my normal statements. Only one invoice dated 2016-04-07 to 2016-05-07 was investigated , when I was also querying statement 2016-03-07 to 2016-04-07 ???</p> <p>And I'd like an explanation of how I get a figure on my statement of a certain amount and when Vuyusanani from MTN billing dept recalculated it there was a difference in the amounted that needed to be credited to me? How is that possible. Why is there a difference in the amount, who tally's up the statement amount??? Because that's proof enough for me of how we are getting cheated by MTN .</p>
