Upgrade/Cancellation - Nonexistent Service Delivery

At the moment I have been holding for MTN customer service for exactly 39 minutes. This is how it has been for almost 2 weeks now while trying to process and upgrade, cancel a contract and cancel a recurring data bundle. I even went online and changed the upgrade details and no response has been received. The service so, so shockingly bad - I've been with MTN for so many years now and I don't recall it ever being quite this atrocious. At this point I simply want to cancel all contracts and services with them. I attempted to do this online and even the simple password reset functionality on MyContract is woefully useless. It's unsurprising that MTN does not respond to customer complaints in keeping with their dreadful service - given that there are so many other complaints of the same nature. Disgusting.
