Wow, it sounds like you've had quite the journey navigating the Medicare DME process! I can understand how frustrating it must have been to have to switch providers and do so much research to find a reputable one. I'm glad you found a good fit and that the staff at Alamo Respiratory Services were professional and pleasant. It's always disheartening to hear about providers engaging in unethical practices like double billing and rudeness, but it's good to know that you were able to find a trustworthy provider like health insurance PDX through your research. Thanks for sharing your experience and providing valuable insight to others.
