Horrible! Horrible! customer service, would not return calls. My doctor sent me to them for a CPAP Machine. When I wanted to get my supplies they never returned my calls. So I asked my doctor to intervene and the sales rep called me. 11/27/2017 she said she would take care of it and nothing, So I called again 11/30/2017 she said she would take care of it and nothing, 12/6/2017 she said she would take care of it and nothing, 12/12/2017 she said she would take care of it and nothing, They started pointing fingers at the doctor and then doctor said they sent it. If I where a doctors office I would never do business with them. I still don't have anything I have to call my insurance company now to see what can be done.
