No Assistance Double Debit not on my card.

I am a FNB client for far too Long and recently understand what people go through for Double Debits on their cards. I tried following the normal process of getting my money back but always had my query closed and I have all relevant information sent through to them. 5 Open queries have been closed. I am a private client aswell and have been failed right upto the Supervisor of the Private client services (Caswell)
