Banking institution tailored for *****!

Shameful to say the least!!! I do not believe that standard bank should be trusted at all especially with elderly peoples money. My grandfather has reported 4 ***** cases in a space of a month and to date no feedback has been received on either of them. They have allowed more than 40K to be taken out of his account even though he alerted them to the fact that there is ***** on his account. He has changed his cellphone number and updated his entire profile, however, they still allow transactions to be processed to the number after they confirmed that his profile was updated with the new number. They were informed that he is 78 years old and does not use any form of internet or cellphone banking but yet they allow all of this to be processed to his account and they allow it to be activated each time. How is it possible that Standard Bank can be comfortable with the fact that they have left him with no funds to survive and continue to treat him like this after all he did for the Bank. Being an employee of Standard Bank for 40 years and a pensioner for a further 22 years and still loyal to them. That old moto they had that said you can bank on the standard, does not exist. How can a supposed trusted banking institution allow ***** of this nature to continue after 3 cases had already been opened? What security do they have? Do they even care? When are they ever going to respond? Will they pay the medical bills if my grandfather has a heart attack? I'm guessing its a no to all of the above.
