African Bank's Service is appalling!

My father is a resident in a Frail Care Centre for good reason. He requires assistance with day-to-day issues. And that includes his finance! I have a Power of Attorney signed by my father giving me authority to manage his financial affairs. Recently I upgraded my cell phone, and when I reinstalled the African Bank app, I erroneously got locked out of his account. I have been managing this account online for years now. First customer services told me to go to a branch. Cresta Centre branch was unable to help me and gave me an email address to contact. Needless to say, after much correspondence, forms required, documentation presented, they now tell me they need my father to contact them! If he was able to do so, I would not be dealing with this issue. I am unable to pay bills owing as a result of not being able to log into his account! I find this absolutely unacceptable and inconvenient on all levels! If someone is unable to assist asap, I will be closing this account and moving it elsewhere. This after I raved to everyone about your low charges, good interest rate etc. How wrong I was. Ingrid Jonsson ***
