MTN's poor services delivery and appalling response time

Trying to cancel billing on my account with MTN and switch to prepaid has proved to be frustrating and emotionally traumatizing at the same time; sending emails or any form of communication seems like trying to get hold of somebody in Mars. I never imagined that switching a number to prepaid would cause so much emotional distress; despite having fully paid up the contract. NOBODY CARES at MTN, absolutely no-one cares. Two weeks later, I cannot transact on my banking app, have lost out on business as I am not reachable as services were suspended on my line....and following my post on this platform a few days ago; I got another apology followed by dead silence once again!
