American Home Patient Incorrect supplies and incorrect billing Brentwood Tennessee

I have been ordering cpap supplies and receiving oxygen therapy from american home patient for near 20 years or so. I noticed for approx. 2 years or so I have been receiving incorrect supplies along with incorrect billing from them. This started happening along the same time they were merging with Lincare company.

I have talked with Blue Cross Blue Shield about issues with them and they have not had any luck with contacting them either. Right now they owe me back for three months of oxygen concentrator charges for my 20% coinsurance they charged me that the insurance didn't pay on for time failure for filing.

The charge months were for September, October, and November 4th. of 2018. They also send out incorrect supplies and bill the insurance, but I have had no response from american home patient on return postage or directions to return them.

They are basically never answering a call from me or blue cross or returning a replay from a left message. In short this company seems to care little to nothing for me as a consumer or my personal health.
