Nedbank Service the worst

My father-in-law has been a customer of Nedbank for decades. The last month he has been to the branch 5 times. Twice to do FICA, three times to sort out his App. Today we went again. He cannot get into his app as the software facial recognition doesn't accept his face. We cannot get into online banking because the "password is incorrect". When we try to change the password, we can't because it sends a push notification to the App we we cannot access without doing the biometrics. Therefore he has no access to his accounts. The call center doesn't answer calls. Nedbank should be ashamed, he is 89 years old, do you know how much stress this has caused.
