Credit card reactivation

I'm surprised that in this time of COVID pandemic the bank still expects a person to go to the bank to unblock an account that was blocked by mistake. As a person with comorbidities I am scared to go to places like shopping and banks as this can be done electronically. The bank can open an account very quickly over the phone but cant do a simple reactivation over the phone. There's security questions that they can do to prevent ********** behavior if that is what is bothering them.
