Cell Phone Number changed renders internet banking

Went into the Standard Bank Head Office Branch for the second time to change my cell number for internet banking. After waiting 20mins in the queue and asking the teller Nthabasieng if she knew how to change my cell number correctly for internet banking as I had been in before to do this yet it was not done correctly. After re-affirming that she knew and that she had done it correctly I try after the 3hrs wait for system updates and I get a message saying I am not registered for the one time password. I call the call center and after about 10mins waiting I am told I have to go to a branch to register for a one time pin. I am supposedly a Prestige client of theirs. OMW!!! Hopeless!! and I need to make a committed EFT today!!!!
