Worst MTN service

I have been struggling for 3 months to move my account from business to personal. I went to the branch and was assured by Mr. Deon Du Plessis that it is an easy process. I sent him all the documentation required and nothing was done. I've tried to get feedback via email several times and even went back to the branch to see if I can speed up the process. I've been assured it is being dealt with but NOTHING has been done and the debit order is still going off my OLD business account. Nothing has been done about the upgrade I asked for either. I have no other option than to take it further at this point. This is a matter of urgency now!
