ABSA ON LINE CALL CENTER FIASCO

I have a problem with the ABSA on line security system sending a security check to an old cell number I no longer use. Needless to say I cannot access the account then. Every time I call the call center I am advised to go into the branch. I have taken time of work twice, stood in lines for a very long time only to get back to my PC and still have the same problem. On all notifications and marketing etc the right cell no is used, but it is to challenging to change it on this one specific application. Trying to log a complain was even more useless and after being put on hold again and in total spending 25 minutes of expensive airtime I simply gave up. The level of incompetence and arrogance is simply astounding
