MTN absolute poor response to client requests

I have never experienced such poor service encounters with any business than MTN SA . I have been struggling for days now to get assistance with a simple request for my itemised bill. You can never get hold of someone to speak to and even after trying the social media platform ( Face Book) they responded but it took days and then the incorrect information was send. Really this is not on and I wonder where the leadership is hiding as this must surely be the root cause. Please wake up before its too late
