FNB Smart Block taking your money

I had a horrible experience with FNB and money simply disappearing from credit card. I logged into my app and wanted to transfer money from my credit card to my cheque account. When I wanted to transfer an amount, the app indicated an 'error' notification. I logged out the app and back in again. When I looked at my credit card account, all the money that was in there, just completely vanished. I immediately called the fnb ***** line and told them what happened. After 5 calls and numerous simple explanation, I could finally speak to someone that could assist me.

It turns out, that FNB has a system called 'Smart Block Department'. This system simply removes all your money from your account, without any reason, it just clears out your account. When I asked the operator why this was done, he just answered with a smurk saying "well, its just something that FNB does and luckily you dont need the money." How is this possible that FNB has a control over your money, and whether or not you need it. This is internal *****, why was this done, and when am I getting my money back? How is this even legal? If people commit ***** they get sent to jail, but in this case, FNB simply does whatever they want with people's own hard earned money. FNB needs to sort this out immediately! This is unacceptable and ***** and they need to answer for what they have done. I dont understand how they get to play with people's lives and its simply just brushed off, and the staff at FNB are aware of this, but it is as though this is a standard thing to do, take from people! No one at the ***** department has taken this seriously, this is absolutely disgusting behaviour from FNB.
