FNB are dumber than dumb

I am a Private Client of FNB. Let me explain how I am stuffed around by their nonsense. I want to purchase a chair. I go into my app and up my spending amount. I authorize my change and it is accepted. I then go to the Office web site and try to process the payment. Declined by FNB (some ***** intervention?). I go around and around trying to get this payment processed as I know the officegroup.co.za is legitimate. Then my card is blocked by FNB. Then I spend about 20 minutes trying to get through to FNB Card to unblock my card. I am asked to authorize myself multiple times via their banking app. I put in fingerprints, card number and pin etc., AFTER logging into my app. Finally my card is unblocked. Then I am told I need to speak to the ***** Department who blocked me to unblock my transaction. I get transferred and then lost in the system. I call back and am asked to authorize myself. I do this a number of times. 1 time, is exactly before I finally get through to a consultant who promptly asks me to authorize via my app that I am who I am. I ask to speak to a manager. I am put on hold by Chadwin. 15 minutes later I am back to original who again asks me to appove myself via my app... I am told by Chadwin that they will get a manager to speak to me but for now I must provide my card information and they will stop the block of my purchase for my goods trying to spend my money. I am still waiting for a manager to call me back. What was a simple transaction to a legitimate site has taken be over an hour to NOT DO. I ask Chadwin why the purchase was blocked and he cannot tell me. I mean ***. And this ******* comes shortly after I cancel one of my 2 cards to save very high service charges only to find my 1 card is now generating higher service fees than 2 of my cards. FNB I used to like you but I am getting very very very tired of your illogical BS.
