EXTREMELY DISAPPOINTED LONG TERM CUSTOMER

I have been with FNB from the time I could own a bank account, all has been going well until I made the biggest mistake of my life and moved my Credit Card from Absa to FNB. I am on the Phone with FNB 3 to 4 times a month, querying double debits and unauthorised transfers which are all blamed on some system. A few days ago your agents called me to advise that my Card was a little over the limit, we made an arrangement that I would pay the amount on the 15/01/16. This morning 05.01.16 I logged into my online banking and made a payment to my credit card. About an hour later FNB debits money from my account which was transferred to my Credit Card. WHY? I have been on your phones now for over an hour trying to establish whats happening. No one seems to be able to explain, I am being transferred from Dept to Dept, holding for close to 30min only for someone to come and drop the line on me. As I type this message I am on hold now for 26min once again in search for answers. Last month FNB debited my account twice and again blamed it on a system error. I am sick to the gut with the service I am getting from FNB. No we wait and see if it will take another 30 days for someone to respond!!!!
