By far, with the possible exception of the irs, this is the worst customer service department I have ever dealt with. My dr. Prescribed portable o2 for me in nov 2016. Apria then states dr did not put flow rate on script. Dr re wrote script. Then apria tells me the dr needs to send documentation as to why I needed it. Dr sent that it. Apria then said dr needed to do a specific test and send that info in. The dr did that. Then apria calls me and tells me they will be out the following day,.. By now it is jan 9, 2017.. They did not come out or call me. I called them jan 12th and was told it was being processed. My humana nurse then called them on the 12th as well and was told they would be calling me back that same day or following day to set it up. They did not call either day so, today the 13th my nurse called them again and they said they needed to hear directly from me. After being transferred and put on hold by various people, someone (Monique) proceeds to tell me I need a prescription from my dr... At this point I am pushed to the end my patience. I asked to speak with a supervisor. I was put on hold over 20 minutes only to be told no supervisor is available as they only have one supervisor (I find this very hard to believe!) that being said, monique states a supervisor will call me back with in 48 business hours,.. Since this is friday afternoon and monday is a holiday,.. I won't hold my breath (Half assed pun intended). I wish I had different option of companies to deal with, unfortunately this company is the only one that my insurances cover at this time.In reading these reviews, I don't know how they stay in business. Terrible company to deal with!! Avoid if at all possible!!!
