NOT EASY TO TRY OPEN AN FNB ACC AND MOVE OVER

I am not sure how your online services "Try" make a process better to open an account. I am trying to open a FNB account and I have no clue what is going on, but errors keep popping up and asking for log in details. I have been trying to use logins from when i was a FNB customer before but it tells me that it cant be processed. Do you guys screen and choose who you want to be a customer and who you dont want to be a customer? My wife and I were both looking at moving over, but it seems to be a hassle!
