change of banking details

<p>I went numerous times into a MTN office to change my banking details as I closed my cheque account. With no response. Every month it still goes back to the old cheque account , and then it declines and I have to pay penalties. I went into the Middelburh Eastern Cape branc again last month and she shows me the details is changed, and once again it went back to the old details and it declined again!! on phoning the MTN helpdesk they told me to go to a MTN branch which I did many times and still its not done!!! I need this problem to be solved immediatly. If somebody can phone me regarding this issue on ********** or ********** Judith</p>
