Shady Claims Process and Questionable Average Customer Rating Score

Discovery Health automatically declines submitted claims with vague responses (date/practice no. not visible) on more than 2 claims. Their service is starting to become shoddy and their claims process is more shady. Seriously thinking about moving my portfolio away from a company that has low business/moral ethics. Why do I have to call in to the call-centre in order for Discovery to do what is required of them.
