BILLING STILL NOT SORTED OUT

Thank you, Nompumelelo, for responding. However, you failed to do your homework before doing so. I'm well aware of the charges that change once you're out of your 24 month contract. Problem with your response, though, is that I'm NOT yet out of my 24 month contract since my last upgrade. Even though I was due for an upgrade when all this nonsense happened from your side, my contract only expires at the end of June. If you check your records, you'll see that my last upgrade was done on the 28th June 2014 (as per your friendly call centre staff), which means that I'm not due for the increase in Promo fee yet. So, for the very last time, get your act together, credit the overcharge, and damn well wait for the right time before you slap your additional fees onto my account.
