FNB : Double debiting Credit card

Being a Private wealth account holder i would have expected me to get better treatment, I have a credit card and after years this month i get a message stating my account is arrears,.... which it has never been, which is strange as every month i Transfer roughly 20-30K into my credit card around the 25-30th of each month,and i have never had a debit order off not once on my account nor have i received any messages why now?? (surely something has changed) now all of a sudden I am being called regarding my debit order and arrears which is very strange, someone, not me has gone into my account and set the debit order to the 17th without my consent. Yesterday after following up with my Private bankers i was told its has been sorted, however this morning my account was double debited.

honestly its like FNB is going down the drain and are not bothered !! im really ****ed off, its not only now but been a while where FNB customer service sucks!! My PB is Mathonsi, Mesuli and i Expect her Manager to contact today the reason why i am putting this on hello peter as i expect proper feedback.
