False information

I received a telesales call from mtn and i was offeres two smart phones at R69 a monthm When i asked the agent which phones i get to choose from, samsungs and iphones were some of the options given to me and i was informed that someone will be in touch to make me choose my phone. On Friday 2 phones were delivered to me. ZTE? The agent **** to me for the purposes of the sale. I want what was promised to me. And if you cant deliver my wish, i want that phone recording seeing as all calls get recorded and i will then take the matter further.
