Poor Customer service from MTN Mall @ Carnival

<p>I have been a customer with mtn for many years and went to upgrade my phone on the 2/4/2016. On the 08/04/2016 I took the phone back to the mtn store at the mall @ carnival. The agent that received the phone was Rodney Sithole. On enquiring about the phone we found out that the wrong date was put on the documents stating that the phone was only given in on the 10/04/2016. After a long struggle we were told that they are going to replace the phone but that we will have to wait as they do not have stock. Untill now we have still been waiting for the new phone and when we ask the store what is happening we are told that we must phone and follow up. We where given the following numbers to phone: 808 / ********** 667. When we phone to follow up on when the new phone will be at the store we where told that the store must phone and follow up. I have now been paying for 3 months for a phone that I can't use. I want this Upgrade to be cancelled with immediate effect and want nothing more to do with mtn. They are very quick to deduct money from your account but not so quick to solve their mistakes and replace the phone. </p>
