MTN South Africa - A *****

MTN South Africa is a *****. I've signed for My MTN Choice 5GB promotion where I was supposed to get 20GB day and 20GB night data for 24 months. However, February they decided to give me only 5GB. When I ask them, they keep on saying your query has been escalated to the relevant department. And I should wait for 3-5 working days. Now it's day 12. Maybe their days is like that of our Lord where one day is like thousand years.
