Bonitas NOT paying for Double Lung Transplant patient aftercare tests.

My wife is a double lung transplant recipient and Bonitas is refusing to pay for her aftercare tests and medical expenses after approving the double lung transplant in the first place, basically giving her a death sentence as it is impossible to pay cash for the aftercare needed to maintain a double lung transplant patient. It has now come to a point where they are ignoring my e-mails and messages and I have nowhere to turn to.
