Past the point of frustration

This is my second complain regarding MTN. I am waiting for almost 5 weeks for my request to be sorted out. They keep telling me they will log the complaint and nothing gets done and speaking to supervisors at MTN Direct is of no use because nothing still gets done. Now I am told that they have 4000 complains to attend to and that the Supervisor has gone on leave, can you believe this!! So do I wait another 5 weeks before I have to call again to hear that they will log a complaint? I am highly frustrated at present with their service. MTN \Everywhere you go"people are frustrated. """
