Unable to use my Absa Internet Banking account.

Whenever I log into my Absa Internet Banking it gives me a code that I should enter after entering my account number and pin code. Upon entering the code it clears all the information an askes me to enter the same information again. It just never lets me in to my internet banking. I've called both telephone and internet banking and none of he departments were able to assist me. The person I spoke to in the internet banking department told me that He can not see anything wrong on his side. It gives me an error message reading \Invalid credentials entered. Re-enter the required logon information.\" I know that I'm entering the correct account and pin number so what could the problem be. I've tried resetting my pin it also does not allow me to do so. I've tried creating a new account it does not allow me to do that either as it picks up that my ID number is already registered for internet banking. Please assist...."
