Bad service MTN Customer Care

I have trying to get my contract to go via debit order since last year, I have been to 2 stores where I had to pay and then try upload the system to debit order. The lady at MTN Chillier Lane advised me to contact the customer service, which I did. They requested a lot of info from me which I provided and even the date of which i would like my debit order to be start, Today it is the 3rd and nothing has happened, The lady I was speaking to on mail was Thobeka Maya, I am very unhappy with MTN customer service as this will result in my account running into default and also I will need to take time during working hours to go pay my account, even if it is during the weekend I will have to stand in long ques just to pay my account. It has been almost a year now trying to get this resolved and nothing has happened,
