STANDARD BANK DOES IT YET AGAIN!

A MONTH LATER AND I DON'T HAVE ACCESS TO MY SISTER'S ACCOUNT YET AGAIN!!!! Please Standard Bank, I am asking for all the time that I have spent going into branches, calling you and emailing back again because there is really no way that that time could have all been spent in vain.First,my sister sets up a travel wallet for her immigration and gives me power of attorney to transfer money from her bank account to her travel wallet, she takes me in there and tests it. The woman behind the counter asks me for my sister's passport!!!! Yes, while she was supposed to be out the country. Once my sister leaves, I try it and get turned away by Kgomotso because it's too much money and it needs to clear before I can transfer it but she will call me back when it's clear - you guessed it - no call! My sister in desperation transfers the money into her credit card and get's bank charges amounting to R2000 because of your bank. As new immigrants they needed terribly. I try and do stuff on her homeloans and get told I don't have power of attorney. It's sorted a month ago and a payment of R45 149.03 is made and now homeloans has no records of it! I cannot deal with this everytime, please help!!!!
