MTN needs to do better to make processes easier for consumers

Having a very teribble experience with MTN on my insurance claim . After being violently ****** of my devices I have contacted them multiple times to assist with my claim and im getting the same feedback . Being sent from pillar to post. Placed on hold for long periods of time, resulting in me having to drop the line and call back. I have expressed that these devices are needed for me to earn a living and this dont care attitude is really off-putting. I need a higher manager to make contact with me urgently as this is now incurring extra cost on me, having to call in every time and being placed on hold
