Bad debt calls for dead person

My ex husband passed away in October 2024 and since then, every day, I get a phone call to ask when the bank account will be settled. So every day, I have to explain that he passed away and that the executor will be in contact with you... no history notes are made obviously or the staff just dont read before calling me and I think this is unacceptable for such a big organisation because every day I have to go through the same thing. Now lately, what your staff is doing, is they call, wait for me to answer, and then say "can I speak to Rikus" and then THEY put the phone down. This is harrasment now and unacceptable. Can someone higher up in Discovery please see that this now stops. It is unsettling for me and I really do not have any ownership over the credit card. As mentioned, he was my ex husband.
