Here we go again

Last year I attempted to no avail to get Netstar to chance my debit order to a different bank. After a huge issue it was promised that my account would be reinstated and Netstar would contact me to get my new banking details. This was naturally not done and I thus through the customer portal sent a request to this effect. Again no response. I then updated my banking details on the customer portal. This despite Netstar has now two months in a row again debited that same old bank account, which is dormant and which now incurs R 180 per bounced debit order charges...
