POOR CUSTOMER SERVICE

I always had a really positive impression of FNB however this has changed with my recent experience. I paid R3000 into my credit card on the 31st July and then they still took a further R2452 on the 6th August. When I queried this they told me that I paid it too close to the debit date. How is it possible that the payment is going from account to another (WITH THE SAME BANK!) and they tell me that I paid too close to the debit date so that's why I am now paying a second installment of nearly the same amount which I paid in already????And furthermore I now have to wait a further 24 hours for thet.money to reflect on.my credit card as being pai***** NOT CONSIDER BANKING WITH FNB! THEY HAVE LOST THE CONCEPT OF "HOW CAN WE HELP YOU?" AND ITS NOW ALL ABOUT HOW CAN WE HELP OURSELVES! And furthermore when you chat to any of their service advisors, the experience is like talking to a robot. They offer no apologies and do not acknowledge your dissatisfaction!They simply end the chat by saying "Thank you for contacting FNB and if you have any further queries, please let us know".They are very customer unfriendly and lack the ability to acknowledge the customers dissatisfaction and more often than not the chat is ended by the agent before you stop responding/talking on the chat, which I find to be quite rude and impolite!
