PATHETIC SERVICE MTN CORNUBIA

Pathetic Service by MTN Cornubia. I signed up for a Black Friday deal and to date the promotional offer hasn't been updated on my profile.

No one answers the Cornubia store number and the servicing agent says that this mistake has affected numerous users and their operational manager is aware of the issue.

How is MTN rectifying their error? Why must the consumer bare the consequences of a business mistake? How do we escalate as the servicing agent doesn't want to provide us with guidance? It's now over 3 weeks and no resolution of this however it was raised week's ago?
