Nedbank have no regard for illness

My mother has a Nedbank account. She has recently been diagnosed with Dementia and also has infazeema. She is in a wheel chair and is permanently on oxygen. We managed to get her into the bank(which was not a small feat) in order to give my Dad signing power on the account so that he can access the account. The debit card now expired. My dad went into the bank to get the new card. No. My mom has to come in. The waiting time is so long that her oxygen dropped down to below 70. No one cares. What is the point of getting signing power?. Pathetic service. My mom's health issues are serious. They don't even try to make a plan to help. Disgusting.
