Cant access my business banking account

I am writing to complain about the service on my business account that was opened in August 2014 at Rivonia branch. Since I opened the account I have not been able to access my internet banking all the time. Today is the 5th time that I try to log on and get an error message \ Invalid credentials entered. Re-enter the required logon information.". When I contact the call center they says it has to do with FICA docs missing. Now I have been into the bank personally 3 times with these docs and still get kicked out when I try log in a few days after it is supposedly \""fixed\"". Why does it keep rolling back or changing? And when I do get access to my banking then I also have problems doing EFT's to my suppliers"
