shocking service

I'm disgusted by what Jane did to me? The manner by which she tried to sell me MTN'S product I never said that I wanted to buy it. Jane said that she was going to email me the details and that it will cost me R39.99 per month and then said goodbye. That's when I shouted at her saying that I never agreed to that and that I didn't want anything from mtn as she tried to de***** me into signing up for something I did not. I asked to speak to a supervisor or team leader and then she hung up on me. I tried to call her back on the number she called me but it did not work. I did not get the email she promised which had all her details on it. I'm fuming and disgusted by that service and the manner by which they tried to hoodwink you into signing up for something you did not agree to
