Can't seem to change my debit details...

I have been trying to change my bank account details for the past 3 months.<br> I have spoken to 3 different people and given them my new details<br> but every time the end of the month comes 8ta try to debit my old account that I am no longer using.<br> so I keep getting fined for a bounced debit<br> I tried holding for the supervisor Lungi Cele but after about 10min I gave up.<br> I tried emailing Lungi Cele but her inbox is full so my email didn't go through.<br> <br> I am now going to have a total of 3 bounced debits thanks to Telkoms *********** useless staff who don't know how to do the jobs they are paid to do.<br> <br> but should I be surprised at this level of ***********s...<br>
