Disappointing reaction from Standard Bank

1. Bank has not linked one of my accounts to my cellphone app. 2. Bank cellphone app does not allow account holders to close an account. 3. On opening my app I find that all beneficiaries have been deleted, so cannot pay accounts. 4. Bank call centre advises me only a personal visit to local branch will solve my problems. Closest bank branches at Stanley Street and Greenacres are closed due to Covid. I am 80, and therefore rely on internet banking and my cellphone app. I am most disappointed with the interaction and lack of assistance I have received.
