Declined Authorisation

We got pre authorisation for my Partner (who in the interim passed away) for a hospital visit. They did a whole lot of tests etc and in the end they found out he had stage 4 cancer. At the end Discovery declined the authorisation which I understand was to a waiting period. That is not the issue. But for a month and a half I had to call every few days to see what is happening and to date I still never received any kind of notification to say it had been declined. Surely they should let a person know what is happening and at least give some kind of explanation as to why
