HomeLoans

I switched my debit orders to another bank, so Nedbank HomeLoans decided not to switch before they verify that I initiated the change, they sent a message to say I must call but to my surprise when I called none of their agents were able to help they told me that I can't change the banking details, I must use their app or go to a branch, I told them that I don't bank with them so I don't have their money app, I only have a HomeLoan account with them and I asked if I can't change via the phone then why did they send a message saying I must call, I'm so irritated with *********** service providers, so I guess the debit will bounce and I'm not even bothered because they are the ones who are ***********
