False sale of goods/service

On the 11 July 2018 I confirmed an upgrade of my MTan contract package to a data contract for R89 a month. Thato Hadebe, a Retentions & Winback Agent for MTN assisted with the upgrade. With this she said I would receive 2 gigs of data to use during day time and 2 gigs at night.

She then also said I have an option of choosing between 1 gig extra monthly for 12 months or a 100 voice minutes monthly for a 12 months. I chose a 100 voice minutes.

I would like to bring to your attention that I am only receiving data and I have not received the 100 voice minutes. I have sent numerous emails to Thato asking her to have this issue resolved, however I have had no joy from that. I would like to have this resolved the soonest.
