Worse service that an ******* roadside clinic

My wife has brain cancer and stroke. As a result she is fed through tube which need to be changed a least every 6 months. It is now more than 1 year since they we put it. I have been trying to get Discovery to approve the process over the last 3 months. Nobody seems to have a clue what to do. I have been pushed from pillar to post… fill in docs…already done…. talk to oncology…. they don’t know what to do…. send us the pro-forma invoice… done…write a formal complaint … done, no response
