Incompetency at it's best

I am so disappointed with Cell C with their *********** consultants. I have been trying to change my banking details with them for 2 months now, their consultants can't do it over the phone after several attempts with different consultants who couldn't explain why their system is unable to change my banking details. I resigned to going to the branch. When I went there 2 weeks ago the consultant who assistant me told me that it was because it appears as if I have recently changed my surname. The surname on my bank statement did not match what they had on the system. I agreed and I gave them a copy of my new ID, Marriage certificate and my new bank statement and was told that it can't be changed immediately I should follow up after a few days. I didn't give them a few days gave them a few weeks and when I called them this morning they still haven't changed it. The lady I was speaking to is adamant she can change it, I am telling her I have been through this whole process with a few other consultants who were unable to assist me I am even telling her what the branch said was the problem. I am explaining to her that I am really ****ed, if you guys can't help me over the phone and the branch is unable to help where else should I go. She’s like “no we should do it again” I took a deep breath and we did it again and guess what?? She couldn’t change it herself and told me it was because my branch code is incorrect so system is unable to pick it up. Which is nonsense ABSA has a universal code if your system is unable to pick up my branch code surely it can pick up ABSA universal code not to mention that I submitted the new Bank Statement at the branch and all the details are were there. So in the meaning time I am stuck and paying bank charges on a bank account which I am not using, that would like to get rid of all because Cell C is still debiting my account there. Mind you when I moved to ABSA two months ago ABSA offered to change all my debit orders for me. All other companies change to my new account without any sweat but not cell the special child. Guys I cannot be running so much after you to get your money that flipping debit order will be bouncing this month.
