Horrible banking experience

I opened an account with FNB and the agent who assisted me did not set up my profile correctly as explained to me by another agent as I was unable to set up my online banking, after 4 trips to FNB and hours on the phone they eventually fixed my online banking. Now for the first time I transferred money into my account and now my account is on hold and I am unable to withdraw my money or make any payments. I now do not have any access to my own money! I have been on the phone for more than a hour and been transferred between digital banking and premier banking 6 times! The line is so bad the agent finally being able to assist me can not even hear me and then simply sent me back to my online banking and said I must use the online chat. Since I started banking with FNB I have only had problems on problems and it's been 2 months!
