MTN IGNORES BILLING LIMIT

I have a cell and an internet account with MTN, and set a 'Self Service Spend Limit of R1,500 pm<br> MTN decided that i have used additional data on my internet line and debited my account for R5,353.23 on 31 August 2015, and despite acknowledging their liability on calling their call center, have failed and now refuse to pay it back! I have spoken to several other people, who have had the same experience. <br> Answer: Avoid MTN, or buy your own phone and buy airtime to avoid theft from your account.
