Imcompetent Standard Bank

Most *********** useless part of Standard Bank ever. My mother had a Standard Bank account for almost 60 years. She was also a member of the Standard Bank UCount rewards programme. She passed away on 6th December 2020 and Standard Bank was informed of her death with all the necessary documentation that was taken in in person. The accounts were officially closed. UCount keeps on trying to take off payments on an account that does not exist and have been informed several times that the account holder is deceased. Still they keep on trying to take payments every month and sending strings of emails. How *********** can you get? It is all the same bank, linked to the same information system. How many times does a person need to contact them? What do they expect? Do I need to take my mother's dead body and dump it on their counter?????
