MTN SA DISGUSTING SERVICE - 3 Months no solution

I requested an upgrade in November 2020, they sent me the wrong phone. Hazel Ma***ane and Melissa Hartman, ignore all of my emails and calls. It is now Feb 2021, I still do not have the correct phone. What is the point of having "Area Managers" If I can't even speak to them directly to assist me. How is this my issue when it was MTN's fault to begin with.
