MTN advertise package and activate wrong one

Mtn had an advert on there website that read Mtn MyChoice anytime 200 with 200 minutes, 500MB and 300 SMSs. I asked my son to do online application for me and he was given reference ***3, automated email response on a Sunday, February 7, 2016. Because of the disclaimers made on the email regarding the online application, I called in Monday, February 8, 2016 while the adverti*****t was still alive online and made the application telephonically, it was approved and parcel delivered within 3 days. When activated, it was activated as Mtn Anytime 200 with R200 airtime value and not what I had app**** for. Calling Mtn thereafter to correct has been a nightmare as I get transferred from one person to the other, kept holding for lengthy periods and get promises to call back that are never honored. I have been given a few reference numbers and when calling back keep getting conflicting explanations. To date the issue is not resolved, nearly a month later but I have been billed and my account debited. Sunil the supervisor is outright rude as well. I also made an online complaint on the Mtn website, got an automated response with a promise to give feedback, but never got any feedback.
