MTN disappoints yet again

Once again MTN disappoints. I really do not know what a person must do in order for MTN to get just one thing done. For months I have been asking for my debit date to be changed. The screenshot below is a direct message I received confirming that it has been changed. When I called this morning I spoke to Sphiwe and he said nothing has been changed, he then “changed it on his side” and now its effective from November. Why was it not effective already since I was told that was changed for October. The other thing that makes it all a drag is the attitude of these consultants. They are rude and show no interest in helping. Every month I call and enquire and I am told that it has been changed. So what must happen now? Im getting really tired of MTNs incompetency and lack of actually getting something done
