MTN ZA offer of Disney + not legit?

Downloaded MTN ZA App. Got offered one Month FREE Disney + subscription. App**** for it and was told I would receive an sms. I am still waiting for that sms from MTN. I did however receive an sms from who knows where or who informing me that my Dsiney + subscription has expired! I have proof that this offer was made from MTN ZA app ( which I doenloaded from Google Playstore) I have sent an email to MTN customer service, with the screen shots of the evidence that I did the subscriotion on the MTN ZA app. They then rep**** for me to send my cell number with which I subscribed for Disney +. I did so and have still not received any answer of what is going on. For the public's information: do not even bother it seems to not be a legit offer so far.
