Dishonest agent selling contracts and incorrect billing

Extremely disappointed, renewed my phone contract two months ago and was promised by the agent that I would get my additional call time minutes and data bundles with my monthly subscription. I confirmed 500% that this will be the offer as I've had this set up on my previous 24 month contract. My monthly subscription increased more than R200 for this and I've been billed the extra amount but no data Called the contact centre, pillar to post, sending me to the wrong departments and no one knows how to assist me. After an hour of trying and rexplaining myself no assistance I've asked for the call recording and reference numbers and no one knows how to assist me The agent said she would call me back 10 min back because she doesn't know how to assist me and still no call I made sure that before I renewed my contract this would be the set up, this is extremely dishonest and no one can assist me You cannot hear anything because the call centre is extremely loud and you have to repeat yourself over and over Now they cannot help me because I've already upgraded and charging me for nothing. I need assistance and need the call recording for the lack of quality from the agent
