Nedbank headache

I had a problem with the Nedbank money app for over a year, which limited access to my account. I visited several branches and none were able to assist with the errors i had encounted. I finally decided to leave the bank and join another. I requested from Nedbank to change the debit order dates for my credit card and funeral policies, as my salary date had changed. They continued to debit the incorrect dates, thus incurring fees. This morning I received an sms that my policy is in arrears.
