********** Billing, Poor Coverage & Lack of Customer Service

It's the 2nd time that I have been wrongfully advised by their stores on the upgrades of my corporate client lines and even though I have raised the issue with store management, regional area management and the CEO's office, i am still bearing the financial implications resulting from the inability of their representatives. I have now been sending communication back and forth for the past 2.5 months and still do not have a resolution to my problem. I have also raised a coverage issue in this time and whilst MTN has noted that their tower is down, it doesn't seem like any effort has been made to fix it in over a month. So I am being billed more than I agreed in store when upgrading, without a package specified on my signed contract, with poor coverage for 2.5 months, empty promises from MTN staff and nowhere closer to having any of it resolved. It seems the don't care attitude filters from the CEO down as he is cc'd in all of my emails but has yet to reach out to me despite the lack of basic customer service being provided by his brand.
