Customer care non existent

I have two contracts with MTN, one for my personal use, and one that I took out for my daughter when she was still at school. The debit order for my daughters account was on a different bank account, I tried more than once to change that to my bank account by visiting the Three Rivers branch, but they only advised that i can only change it when I upgrade the account. Then the debit order failed to go through on that bank account one month, and we went back to MTN Three Rivers whom advised us to pay the money into MTN's account with the cell number as reference, which we did and continued doing it that way. Now the phone is suspended and I am blacklisted because of it. Now my issue is getting this resolved, I logged numerous calls by dialling 135, but they get resolver the same day without anything being done about it. I sent emails to customer care, they also just close the calls. Then the latest case where I sent an email, they rep**** to me and said that I should email the legal department, which I also did 3 time already and had no response at all in weeks of trying to resolve the matter. My daughter is in the process of finding employment, but due to the fact that MTN wrongly terminated the line, there is no way of contacting her. I have never seen such poor customer care service as this.
