Unprofessionalism at Standard bank

I have been having problems since Standard Banks upgrade over the weekend. I cannot access any accounts on the app and all my beneficiaries are not to be found. I have been into a branch twice, spent 2 hours on both occasions and nobody can assist. The call centre does not answer as well. This is really fruit and an absolute inconvenience. Standard bank has messed up. Considering moving my accounts to another bank, cant put up with such pathetic service. The consultant at the branch was trying to help, but he did not know how,so employees are also in the dark.
