Disgusting service from MTN Cape Town International Airport

I am having an absolute sickening experience with MTN at Cape Town International Airport.

On the 23/09/2018 at about 15:30, just before my flight, I urgently needed to buy a new cell phone that had the dual sim-card functionality. I spoke to one of the consultants, Shameelah, and told her that I needed a new phone. Before purchasing the phone, my boyfriend and I specifically asked her if the Huawei P20 Lite had dual functionality - and she said yes. We proceeded to pay for the phone and I left the country for 3 weeks. Upon returning and needing to use my second sim-card, it did not work. Mind you, I am paying extra for the additional sim-card. After hours of struggling with the sim-card (thinking perhaps I did not insert the sim card correctly) I came to the abrupt realization that the phone does not have the dual sim-card functionality as Shameelah falsely indicated.

I proceeded to call the MTN at Cape Town International Airport and spoke to the manager, Thandi, who said she would speak to her manager as I want a refund. A few minutes later, I received a phone call from Shameelah who proceeded to bicker on the phone with me for 6 minutes and accused me of being contradictory. To my knowledge, she is not the manager. I assured her that this would be taken further. I will make a noise on every platform until my complaint is seen to - and resolved.

I am disgusted with the way the MTN is handling this and I demand a refund. I was given a phone under false information for a quick and greedy sale. I spent my money buying a device that does not even have the feature that Shameelah told me about and I am furious about this.
