Telling lies to get clients

My Name is Thamsanqa Ncube I received a call from a guy called Nokhaya offering me a phone that comes with 15 gig data. He asked to chose a phone and i chose A28. He took delivery address details and i completed the application with debit check. He then told me the data will be added on my current number. Out of my suprise, when i wanted to make a call my voice minutes and my data all gone. I called MTN they confirmed that my number has been changed to a data sim( how stupid is that) 😡 and there's no phone on this contract its data only. I stayed on the phone for more than an hour trying to call them to cancel this order because i agreed on a phone contract not data only.
