ABSA Online Banking Woes

I am absolutely horrified with ABSA's service regarding a Credit Card and online banking.

I went to the ABSA Kolonnade Branch to activate my new credit card which was done quickly and without hassle. I afterwards asked the lady to assist me with my online banking as I get "Invalid credentials entered. Re-enter the required logon information." error message when I try to log in. She checked the system and said that my new card is activated and that I will be able to login to ABSA online banking. When I got home, I tried and got the same error, I then phoned the helpline and was assisted by an agent telling me that my profile is incomplete and my mobile number must be updated....this after the lady in the ABSA branch asked my mobile number. I asked if she can update my mobile number as I had to take a half day leave to get this done and her words " sir you need to go to a branch to get this updated".....I think it is ridiculous, to go to a ABSA branch to get something as small as a mobile number updated on a profile. In this day and age with us being asked to stay out of shops and malls ABSA forces us to go to a branch for something as small as a mobile number to be updated.
