Should I take my business somewhere else?

What a horrible experience with fnb online banking. I traveled to the us and did notify them about this. Then I tried to login into my banking app and it told me that I have limited permissions and I have to call a number to activate my account? Do I called last week and they told me 24 hours and someone will call me from the admin team. The weekend passed and Monday I called again. The lady told me again that someone will call me in 24 hours on my USA number. Tuesday still no call so I called again 24 hours later,this time a guy told me 48 hours and I need to fill out a form and send it to the email address on the form and he gave me a reference number and someone will call me within 48 hours. It has been more than 48 Hours and this morning I called again and they transfered me once again and after waiting for two hours I had to hang up because international calls are super expensive and with the seven hour time difference I can only call early mornings on this side before work starts. I still can not access my online banking and no one has been trying to even call me. Should I just take my business elsewhere. I have been a client of fnb for eleven years and do not appreciate this.
