Impossible to get a pre-authorisation at discovery if you can't speak

Been a member of Discovery for well over a decade, and for the very first time I needed help getting a pre-authorisation for a procedure and a month later no one can help all I am getting are bots sending me the same responses even a complaint on their complaints site has yielded zero. I've completed all forms sent to me returned them multiple times tot he addresses provided to no avail. I even tried the WhatsAPP number for help, which gave me another contact to send my documents and 2 weeks later, I have not heard from anyone. Fed up with this type of treatment, maybe its time to check for alternatives.
