Fnb - money grabbing *******ly

I opened a new FNB account to manage my monthly payments according to salary date and additional income. I moved necessary debit orders. No authorization was given to Fnb to change a personal loan debit order from my old bank account to the new account. They now debit me causing other payments to reject. Tried calling and no freaking department can help to remove debit order. Collections supposedly the only department that can help but you never get through even when I sat 45 minutes on the line. ***. This is ******* and according to other complaints like reference ********** NF this is called money grabbing . Thank fnb for inconvenience of now getting another bank to move debit orders so that I can ensure all my payments are gone through and not have rejected debit orders.
