Horrible service

I got a notification on my app that a transaction of R6.5k has gone through my FNB account which I haven’t used in over a month . I call their “24 hour” ***** line to report the issue immediately I had to call 4 times cause no one was attending to my call, mind you is 3am. It’s not like they have a high call volume . I finally get through to a guy who tell me can I call in the morning, he is about to reboot the system. I’m like ####€\?\~\?\£_ !!! He finally agrees and then asks me to go in to my internet banking and cancel the card myself, and that they will let the transaction go through even though it’s reflecting as pending, as they will need to investigate first before they can stop it and that will take 7-30 working days. And then wants to hang up without giving me a reference number for my case? What the point of a 24 hour *****line if we can’t even get through? And then when we report ********** activities you don’t want to stop them ? this is over and above the fact that every month I have to reverse R99 and R125 unauthorized debit orders, which is an issue that most of your customers have and you have done nothing about!
