Absa "NO HELP" line!

My mother (who is almost 90 years old) uses Absa ATM banking to pay all her monthly debts, (she does not have a computer) but due to the nationwide lockdown has not been able to go anywhere. So she asked me if I could register her account for online banking and pay everything for her from my computer, so I did that, but made a mistake during the registration process, so no money can be paid from this account until the limits have been set. I then phoned the helpline, only to be told that my mother would have to visit a branch to rectify the problem, but she can't do that. We are all living in hard times, so you would think that there would be some degree of flexibility; but no, seems like Absa just does not care.
