MTN - Poor after sales client services

Mtn after sales service is a joke (mtn call Centre). Escalation of any service related queries is even worse. You are just moved from pillar to post. Members holding these positions (escalation teams) seem not to understand the issues the 'client' is experiencing and respond without applying thought and process. All you receive is the same answer when clearly the client is not enjoy the benefits he is paying for. Leadership sitting at the service team don't clearly understand the meaning of customer service. Apparently they can't take direct calls and even when you ask for them to call on you, they never do. Even raising a complaint via the complaints line is not dealt within the noted stipulated times. MTN if you really serious about business please sort your service processes out. I expect a personal response from mtn relating to my matter. If this does not materialise withing 7 working days further reputational damage will follow.
