Didn't Debit - No Answer

I called FNB to update my debit order to the last day of the month.

FNB doesn't debit my account and now sends me an sms saying my account is one month in arrears.

I called their contact center and Sibongile tried to help my by making me hold for 10 minutes only to tell me "another department" will help me and "transfers" me which nobody answers.

I tried calling back multiple times with NO ANSWER.

Do I make an EFT, will they debit me after a make the EFT? I don't know as they don't answer their calls!

Pathetic service
