DISCOVERY (FNB) WORST SERVICE EVER

I am hoping this will STOP anyone from ever thinking of opening up a Discovery Card or any FNB Card/Account ever!!! I had my discovery card ****** and reported it immediately. my struggle starts with trying to talk to the right people I was told rudely that Discovery is a different division within FNB after holding on for forever I got the card cancelled. The next day the ****** card was still withdrawing money from my accounts. I reported this to them and got sent an SMS that said the funds would be reversed. Nothing happened 2 weeks later. I called to find out an again very rudely handled by the call center agent and finally the one amount of R2300 was re-funded. there is still an amount of R500 outstanding, I called in twice and was told I would be called it's a week later and nothing. R500 is not even 10% of interest I pay FNB with my Monthly payments so that's not the issue. The amount does not concern me what concerns me it the PRINCIPAL I cancelled my card/account and the ***** was still able to access my accounts using the exact same card. Just so you know I'm a PVT Banker but this is of NO HELP! Next step good by FNB hello new Bank
