Begging for an Invoice every month

A very simple request such as receiving my statement monthly via email is too much for MTN to manage. The "new system" is apparently not able to automatically send my invoice monthly. It's been five (5!) months and the issue has still not been rectified even though they are aware of it. MTN is unable to make a plan and expects me to phone and request my invoice every month? What a joke. Ridiculous. MTN also spams me with useless promotional data specials and the like. Terrible overall!
