Upgraded the wrong contract and too *********** to resolve

<p>I have never seen such incompetence and such absolute disregard to customer</p> <p> </p> <p>MTN have managed to stuff up every single contract I have!</p> <p>1) I received a call from MTN business that my son's data line was due for an upgrade. Number is (063) 40496** last Thursday. I selected the deal with the iPad 5, 2G Data at R319p/m. They did the upgrade telephonically, confirmed on the call it's that number and that the courier will contact me to deliver. The device was delivered on Monday without prior arrangement and left at my house with the lady that works with me BUT I discovered today when wanting to activate the new SIM that they upgrade my son's Voice Line (071) 9018** . I NEVER agreed to this line to be upgraded, the calls can be pulled. I will only upgrade this line later this year. I somehow need this mess fixed. I need the right line upgraded (dataline) and I also dont want issues when I am ready to upgrade the voiceline.</p> <p>2) My line's upgrade was exactly the same story last year, ********** 4** The upgrade would have been done when the iPhone 7 became available. An agent still called me to say she will phone me the next day when the phone was launched, and that we would then agree on what package looking at my data usage/ talk time etc. I got a sms the next day that I was upgraded, no discussoon around what package. Now I'm stuck on a package with way too much minutes and not enough data. I tried calling that day and have a screenshot of where I was on hold for more than an hour, sent tweets to MTN Service, Logged several queries through App without any joy. Now I have to pay R600 extra every couple of weeks to buy data bundles...</p> <p>I am just REALLY frustrated right now! Would really appreciate if you could point my complaint towards someone that can actually fix this mess!</p>
