FNB is *********

I've banked with FNB for over 20 years and have all my accounts with FNB. FNB delivered my new bank card via courier last week. A couple of days later I received an email from the courier asking for (a) ID photo (b) address proof and (c) salary slip - I immediately emailed the first two and asked why they needed the third (there was no explanation in the FNB email or from FNB at any stage as to why these documents were needed). I then set off travelling and stopped to refuel - to find all my cards blocked with no warning!!! Luckily I was able to get assistance but this episode endangered my life. There are plenty of funds in my account and I did everything FNB requested - it has taken two days so far and I've not been able to get through its various automated channels. FNB should be held to account for its ********* actions.
