MTN *****ing my money

My account for April was suddenly a thousand rand more than usually. The data bought and the balance available did not reflect on my account, so out-of-bundle data was charged. I phoned 4 days ago to try and sort this out BEFORE the money is deducted from my account, because I know I will never get it back. No one is coming back to me. <br> My monthly bundles get loaded on the 12th of each month - this month I already have the same problem yet again. Apparently the bundles were loaded late, so already I have out-of-bundle data rates charged. The customer care agent told me this can only be logged as an enquiry once the account is closed. Why can this not be sorted out now? The mistake is not on my side.<br> I am so sorry I renewed my contract, because I have had nothing but problems since my upgrade.
