Cant contact, can't follow up, just non stop computer generated emails.

Father died in 2018, getting emails non stop on a "claim progress report". No idea what to do and how to contact them. I have send many emails over the years to the standard *** general email address with the correct references. I am adding an image with some of the emails. I think I stopped following up at some stage, but their system just keeps burping out the ******* "progress" reports. Simply put, think twice. We had Alan Gray resolve my fathers investments in a matter of months after his passing. Same goes for Old Mutual. so there are better options to those reading this.
