Poor service and Billing

I have been billed abnormal amount for the previous months . I have been sending complaints which are not dealt with if not i will refer to complaints commission.

To my surprise i started getting this abnormal billing when i was told to upgrade my line and i had refuse . If this is not dealt with i will go to the media and also complaints commission.

I have called your customer service and spoke to Mbali Zuke , she had put me on the line for long and hang out the line .

Dont come with your dont care attitude as i will refer this to the ombudsman

My number is ********** if you guys can contact me . The MTN contract number is ********** 106
