Bank Account opened without work permit

My friend is a Lesotho lady who came to South Africa East London last year to look after her relatives kids mayb for 6 months. She didn't have work permit she was using visitors visa. In that time she had to open bank account for herself. She went to standard bank opened account with proof of residence only in East London Vincent Branch. No work permit was required when the new account was opened. This week she is back in East London and she has money that she wanted to withdraw, to her suprise she can't access her funds. She went to the branch and was told they needed proof of residence which she submitted the following day. When she came to submit proof of residence she was told they need her work permit. She told them she doesn't have permit and when she opened the account none was requested. She was told unfortunately she can't access her money until she brings work permit which is impossible for her to get. She asked to be given the money and account to be closed it was still a NO. This is not fair on her as she needs that money to send to her kids and all of a sudden some documents that were not required when she 1st opened the account are now required. Standard bank just give her the money amd close that account
