MTN making money off clients???

<p>We are a small business, thas has 70 contract lines with MTN. From the month of April 2015 through to October 2015 MTN seems to have had a "glitch"in there billing system. They have chosen to ignore all my requests for assistance from 2015 to date. They managed to debit 16k extra just from one of our lines over those 7 months, claiming it was DATA that was used. imagine the total bill of "used data" that they managed to (for want of a better word) "steel"from us. they have not once assisted us and you cant ever get to a ""senior"person for assistance you just get shifted from one person to the next and one building to the next. 2 years down the line and i am still trying to get assisted. I thuoght it right to try and let the bigger compnies with more lines than us to maybe have a look into your accounts and see if your bills changed drastically through those months too, or any months for that matter. not that it would help i guess, because MTN just dont give a **** and you wont get any help with your query. </p>
