Cancellation of MTN contract within 7days

<p>I am new customer with MTN, I signed up for a iPhone 6S last week Friday, at Rosebank and I was assissted by a lady called Maimane last name), where initially I wanted the iPhone5SE and she only had the 64GB. </p> <p> </p> <p>On Monday, I texted her and told her that I would like to bring back the iPhone 6S in exchange for the iPhone SE, however she said she could not assist me. However, I decided, to call customer I dont care line and I waited for long before I could be asssisted, but I was told via the email and by the consultant that I should take back the device and as long it not over the 7day period, will they be able to assist me, to change my plan and the device. But Maimane, keeps on saying that she and the manager will NOT assist me and it is beyond her power.</p> <p> </p> <p>But I dont understand, because I am not happy with the iPhone 6S and I am not just cancelling the contract, but I am only changing the device and the plan.</p> <p> </p> <p>Can someone from MTN assist me by calling me or sending me an email ASAP. This is really frustrating...</p>
