Fradulent - People please be aware of this company

On the 04/06/2018 at 14:38, I received a call from ********** and I spoke to an Agent who told me that this company works with Mtn and I qualify for a cellphone contract. I then gave the agent me details and told her that i am interested in the Hwawei P9 in gold. she then said that i must expect delivery of the device within 3 to 10 working days. The next day I called because normally in every company when you complete a sales deal there should be some correspondence sent to you either in an sms or an email. when i called rewards co they told me that my information was not on the system and i was puzzled because I gave the agent all of my details. i was given this number by the agent and she said that it is their customer services no, ***when i called this number, the person that assisted me was very rude and said i must phone mtn on 083 135. I then phoned Mtn and they also could not find my information or application. to me this sounds **********.
