Horrible customer service. I have been trying to get replacement CPAP supplies for 3 months. The local office was very helpful but there seems to be a disconnect between the local office and the national number for ordering supplies. They could not understand that they had a different mask than was in their records . I picked up the mask at my local office. The person on the phone kept telling me I needed a prescription from my dr for a different mask. The local office made several attempts to straighten it out but every time I called it seems I started over from scratch. After 3 months I have given up and am switching to a different company to take care of my CPAP needs. Straighten it out or you will eventually go out of business.
