Online banking unexplainable problems

My online banking was blocked by the ***** division due to suspicions of *****.To unblock it I had to go the branch which I did and the ***** division told me and the lady that was assisting me from the branch that it has been unblocked and i should reset my login details. I reset them and logged in and even get emails that i have logged into my online banking. However i cannot see any of my accounts or do anything on the log in page as it wants me to unblock my account again. I was at the branch for more than 3 hours and i wasnt assisted. I called the centre the next day and stayed on the phone for more than 2 hours and yet again i was not assisted. I'm reallly starting to get irritated by FNB. I cant even make any payments due to this. It is FNB's system and I expect them to be in a positon to assist me with this but no one seem to know what is happening. I think im gonna change banks cause this is horrible.
